+//!A smart pointer that stores the offset between between the pointer and the
+//!the object it points. This allows offset allows special properties, since
+//!the pointer is independent from the address of the pointee, if the
+//!pointer and the pointee are still separated by the same offset. This feature
+//!converts offset_ptr in a smart pointer that can be placed in shared memory and
+//!memory mapped files mapped in different addresses in every process.
+//!
+//! \tparam PointedType The type of the pointee.
+//! \tparam DifferenceType A signed integer type that can represent the arithmetic operations on the pointer
+//! \tparam OffsetType An unsigned integer type that can represent the
+//!   distance between two pointers reinterpret_cast-ed as unsigned integers. This type
+//!   should be at least of the same size of std::uintptr_t. In some systems it's possible to communicate
+//!   between 32 and 64 bit processes using 64 bit offsets.
+//! \tparam OffsetAlignment Alignment of the OffsetType stored inside. In some systems might be necessary
+//!   to align it to 64 bits in order to communicate 32 and 64 bit processes using 64 bit offsets.
+//!
+//!<b>Note</b>: offset_ptr uses implementation defined properties, present in most platforms, for
+//!performance reasons:
+//!   - Assumes that uintptr_t representation of nullptr is (uintptr_t)zero.
+//!   - Assumes that incrementing a uintptr_t obtained from a pointer is equivalent
+//!     to incrementing the pointer and then converting it back to uintptr_t.

+//! treap_algorithms provides basic algorithms to manipulate
+//! nodes forming a treap.
+//!
+//! (1) the header node is maintained with links not only to the root
+//! but also to the leftmost node of the tree, to enable constant time
+//! begin(), and to the rightmost node of the tree, to enable linear time
+//! performance when used with the generic set algorithms (set_union,
+//! etc.);
+//!
+//! (2) when a node being deleted has two children its successor node is
+//! relinked into its place, rather than copied, so that the only
+//! pointers invalidated are those referring to the deleted node.
+//!
+//! treap_algorithms is configured with a NodeTraits class, which encapsulates the
+//! information about the node to be manipulated. NodeTraits must support the
+//! following interface:
+//!
+//! <b>Typedefs</b>:
+//!
+//! <tt>node</tt>: The type of the node that forms the treap
+//!
+//! <tt>node_ptr</tt>: A pointer to a node
+//!
+//! <tt>const_node_ptr</tt>: A pointer to a const node
+//!
+//! <b>Static functions</b>:
+//!
+//! <tt>static node_ptr get_parent(const_node_ptr n);</tt>
+//!
+//! <tt>static void set_parent(node_ptr n, node_ptr parent);</tt>
+//!
+//! <tt>static node_ptr get_left(const_node_ptr n);</tt>
+//!
+//! <tt>static void set_left(node_ptr n, node_ptr left);</tt>
+//!
+//! <tt>static node_ptr get_right(const_node_ptr n);</tt>

+
+//! The class template unordered_set is an intrusive container, that mimics most of
+//! the interface of std::tr1::unordered_set as described in the C++ TR1.
+//!
+//! unordered_set is a semi-intrusive container: each object to be stored in the
+//! container must contain a proper hook, but the container also needs
+//! additional auxiliary memory to work: unordered_set needs a pointer to an array
+//! of type `bucket_type` to be passed in the constructor. This bucket array must
+//! have at least the same lifetime as the container. This makes the use of
+//! unordered_set more complicated than purely intrusive containers.
+//! `bucket_type` is default-constructible, copyable and assignable
+//!
+//! The template parameter \c T is the type to be managed by the container.
+//! The user can specify additional options and if no options are provided
+//! default options are used.
+//!
+//! The container supports the following options:
+//! \c base_hook<>/member_hook<>/value_traits<>,
+//! \c constant_time_size<>, \c size_type<>, \c hash<> and \c equal<>
+//! \c bucket_traits<>, \c power_2_buckets<> and \c cache_begin<>.
+//!
+//! unordered_set only provides forward iterators but it provides 4 iterator types:
+//! iterator and const_iterator to navigate through the whole container and
+//! local_iterator and const_local_iterator to navigate through the values
+//! stored in a single bucket. Local iterators are faster and smaller.
+//!
+//! It's not recommended to use non constant-time size unordered_sets because several
+//! key functions, like "empty()", become non-constant time functions. Non
+//! constant-time size unordered_sets are mainly provided to support auto-unlink hooks.
+//!
+//! unordered_set, unlike std::unordered_set, does not make automatic rehashings nor
+//! offers functions related to a load factor. Rehashing can be explicitly requested
+//! and the user must provide a new bucket array that will be used from that moment.
+//!
+//! Since no automatic rehashing is done, iterators are never invalidated when
+//! inserting or erasing elements. Iterators are only invalidated when rehasing.

+//! The class template unordered_multiset is an intrusive container, that mimics most of
+//! the interface of std::tr1::unordered_multiset as described in the C++ TR1.
+//!
+//! unordered_multiset is a semi-intrusive container: each object to be stored in the
+//! container must contain a proper hook, but the container also needs
+//! additional auxiliary memory to work: unordered_multiset needs a pointer to an array
+//! of type `bucket_type` to be passed in the constructor. This bucket array must
+//! have at least the same lifetime as the container. This makes the use of
+//! unordered_multiset more complicated than purely intrusive containers.
+//! `bucket_type` is default-constructible, copyable and assignable
+//!
+//! The template parameter \c T is the type to be managed by the container.
+//! The user can specify additional options and if no options are provided
+//! default options are used.
+//!
+//! The container supports the following options:
+//! \c base_hook<>/member_hook<>/value_traits<>,
+//! \c constant_time_size<>, \c size_type<>, \c hash<> and \c equal<>
+//! \c bucket_traits<>, \c power_2_buckets<> and \c cache_begin<>.
+//!
+//! unordered_multiset only provides forward iterators but it provides 4 iterator types:
+//! iterator and const_iterator to navigate through the whole container and
+//! local_iterator and const_local_iterator to navigate through the values
+//! stored in a single bucket. Local iterators are faster and smaller.
+//!
+//! It's not recommended to use non constant-time size unordered_multisets because several
+//! key functions, like "empty()", become non-constant time functions. Non
+//! constant-time size unordered_multisets are mainly provided to support auto-unlink hooks.
+//!
+//! unordered_multiset, unlike std::unordered_set, does not make automatic rehashings nor
+//! offers functions related to a load factor. Rehashing can be explicitly requested
+//! and the user must provide a new bucket array that will be used from that moment.
+//!
+//! Since no automatic rehashing is done, iterators are never invalidated when
+//! inserting or erasing elements. Iterators are only invalidated when rehasing.

-[section:intro Introduction]
-
-A Circular Buffer.
-
-[h2 Description]
-
-The term [@http://en.wikipedia.org/wiki/Circular_buffer circular buffer]
-(also called a ['ring] or ['cyclic buffer])
-refers to an area in memory which is used to store incoming data.
-When the buffer is filled,
-new data is written starting at the beginning of the buffer and overwriting the old.
-
-[classref boost::circular_buffer] is a STL compliant container.
-
-It is a kind of sequence similar to [@http://www.sgi.com/tech/stl/List.html std::list]
-or [@http://www.sgi.com/tech/stl/Deque.html std::deque].
-It supports random access iterators, constant time insert and erase operations
-at the beginning or the end of the buffer and interoperability with std algorithms.
-
-The __cb is especially designed to provide [*fixed capacity] storage.
-When its capacity is exhausted, newly inserted elements will cause elements
-to be overwritten, either at the beginning or end of the buffer
-(depending on what insert operation is used).
-
-The __cb only allocates memory when created,
-when the capacity is adjusted explicitly,
-or as necessary to accommodate resizing or assign operations.
-
-[$../../libs/circular_buffer/doc/images/circular_buffer.png]
-
-There is also a __cbso version available.
-
-[$../../libs/circular_buffer/doc/images/space_optimized.png]
-
-__cbso is an adaptation of the __cb
-which [*does not allocate memory all at once when created],
-instead it allocates memory as needed.
-
-The predictive memory allocation is similar to typical `std::vector` implementation.
-Memory is automatically freed as the size of the container decreases.
-
-The memory allocation process of the space-optimized circular buffer.
-The __min_capacity  of the capacity controller represents
-the minimal guaranteed amount of allocated memory.
-The allocated memory will never drop under this value.
-The default value of the `min_capacity` is set to 0.
-The `min_capacity` can be set using the constructor parameter __capacity_control
-or the function `set_capacity`.
-
-The space-optimized version is, of course, a little slower.
-
-[endsect] [/section:intro Introduction]
-
-[section:example Circular_buffer example]
-
-Here is a simple example to introduce the class __cb.
-
-[import ../example/circular_buffer_example.cpp]
-
-[circular_buffer_example_1]
-
-This example shows contruction, inserting elements, overwriting and popping.
-
-[circular_buffer_example_2]
-
-[/circular_buffer_example_output - there is no output for this example]
-
-You can see the full example code at [@boost:libs/circular_buffer/example/circular_buffer_example.cpp  circular_buffer_example.cpp].
-
-The full annotated description is in the C++ Reference section.
-
-[endsect] [/section:example circular_buffer example]
-
-[section:rationale Rationale]
-
-The basic motivation behind the __cb was to create a container which would [*work seamlessly with STL].
-
-Additionally, the design of the __cb was guided by the following principles:
-
-* Maximum ['efficiency] for envisaged applications.
-* Suitable for ['general purpose use].
-* The behaviour of the buffer as ['intuitive] as possible.
-* Suitable for ['specialization] by means of adaptors. (The __cbso is such an example of the adaptor.)
-* Easy to ['debug]. (See Debug Support for details.)
-
-In order to achieve maximum efficiency, the __cb and __cbso store their elements in a
-[*contiguous region of memory], which then enables:
-
-* Use of fixed memory and no implicit or unexpected memory allocation.
-* Fast constant-time insertion and removal of elements from the front and back.
-* Fast constant-time random access of elements.
-* Suitability for real-time and performance critical applications.
-
-Possible applications of the circular buffer include:
-
-* Storage of the ['most recently received samples], overwriting the oldest as new samples arrive.
-* As an underlying container for a ['bounded buffer]
-(see the Bounded Buffer example, code at [@boost:libs/circular_buffer/example/circular_buffer_bound_example.cpp  circular_buffer_bound_example.cpp]).
-* A kind of ['cache] storing a specified number of last inserted elements.
-* Efficient fixed capacity ['FIFO (First In, First Out)],
-* Efficient fixed capacity ['LIFO (Last In, First Out)] queue which removes the oldest (inserted as first) elements when full.
-
-[endsect] [/section:rationale Rationale]
-
-[section:implementation Implementation ]
-
-The following paragraphs describe issues that had to be considered during the implementation of the circular_buffer:
-
-[h3 Thread-Safety]
-
-The thread-safety of the __cb is the same as the thread-safety of containers in most STL implementations.
-This means the __cb is not fully thread-safe.
-The thread-safety is guaranteed only in the sense that simultaneous accesses
-to distinct instances of the __cb are safe,
-and simultaneous read accesses to a shared __cb are safe.
-
-If multiple threads access a single __cb,
-and at least one of the threads may potentially write,
-then the user is responsible for ensuring mutual exclusion between the threads during the container accesses.
-The mutual exclusion between the threads can be achieved by wrapping
-operations of the underlying __cb with a lock acquisition and release.
-(See the Bounded Buffer example code at [@boost:libs/circular_buffer/example/circular_buffer_bound_example.cpp  circular_buffer_bound_example.cpp])
-
-[h3 Overwrite Operation]
-
-Overwrite operation occurs when an element is inserted into a full __cb -
-the old element is being overwritten by the new one.
-There was a discussion what exactly "overwriting of an element" means during the formal review.
-It may be either a destruction of the original element and
-a consequent inplace construction of a new element
-or it may be an assignment of a new element into an old one.
-The __cb implements assignment because it is more effective.
-
-From the point of business logic of a stored element,
-the destruction/construction operation and assignment usually mean the same.
-However, in very rare cases (if in any) they may differ.
-If there is a requirement for elements to be destructed/constructed instead of being assigned,
-consider implementing a wrapper of the element which would implement the assign operator,
-and store the wrappers instead.
-It is necessary to note that storing such wrappers has a drawback.
-The destruction/construction will be invoked on every assignment of the wrapper -
-not only when a wrapper is being overwritten (when the buffer is full)
-but also when the stored wrappers are being shifted
-(e.g. as a result of insertion into the middle of container).
-
-[h3 Writing to a Full Buffer]
-
-There are several options how to cope if a data source produces more data than can fit in the fixed-sized buffer:
-
-* Inform the data source to wait until there is room in the buffer (e.g. by throwing an overflow exception).
-* If the oldest data is the most important, ignore new data from the source until there is room in the buffer again.
-* If the latest data is the most important, write over the oldest data.
-* Let the producer to be responsible for checking the size of the buffer prior writing into it.
-
-It is apparent that the __cb implements the third option.
-But it may be less apparent it does not implement any other option -
-especially the first two.
-One can get an impression that the __cb should implement first three options
-and offer a mechanism of choosing among them. This impression is wrong.
-
-The __cb was designed and optimized to be circular
-(which means overwriting the oldest data when full).
-If such a controlling mechanism had been enabled,
-it would just complicate the matters
-and the usage of the __cb would be probably less straightforward.
-
-Moreover, the first two options (and the fourth option as well)
-do not require the buffer to be circular at all.
-If there is a need for the first or second option, consider implementing an adaptor of e.g. std::vector.
-In this case the __cb is not suitable for adapting, because,
-contrary to std::vector, it bears an overhead for its circular behaviour.
-
-[h3 Reading/Removing from an Empty Buffer]
-
-When reading or removing an element from an empty buffer,
-the buffer should be able to notify the data consumer
-(e.g. by throwing underflow exception) that there are no elements stored in it.
-The __cb does not implement such a behaviour for two reasons:
-
-* It would introduce a performance overhead.
-* No other std container implements it this way.
-
-It is considered to be a bug to read or remove an element
-(e.g. by calling [memberref boost::circular_buffer::front() front()]
-or [memberref boost::circular_buffer::pop_back() pop_back()])
-from an empty std container and from an empty __cb as well.
-The data consumer has to test if the container is not empty before reading/removing from it by testing
-[memberref boost::circular_buffer::empty empty()].
-However, when reading from the __cb,
-there is an option to rely on the [memberref boost::circular_buffer::at() at()]
-method which throws an exception when the index is out of range.
-
-[h3 Iterator Invalidation]
-
-An iterator is usually considered to be invalidated if an element,
-the iterator pointed to, had been removed or overwritten by an another element.
-This definition is enforced by the Debug Support and is documented for every method.
-However, some applications utilizing __cb may require less strict definition:
-an iterator is invalid only if it points to an uninitialized memory.
-
-Consider following example:
-
-[import ../example/circular_buffer_iter_example.cpp]
-
-[circular_buffer_iter_example_1]
-
-The iterator does not point to the original element any more
-(and is considered to be invalid from the "strict" point of view)
-but it still points to the same valid place in the memory.
-This "soft" definition of iterator invalidation is supported by the __cb
-but should be considered as an implementation detail rather than a full-fledged feature.
-The rules when the iterator is still valid can be inferred from the code in
-[@boost:libs/circular_buffer/test/soft_iterator_invalidation.cpp soft_iterator_invalidation.cpp].
-
-
-[h3 Move emulation and rvalues]
-
-Since Boost 1.54.0 support for move semantics was implemented using 
-the [@boost:libs/move/index.html Boost.Move] library.
-If rvalue references are available __cb will use them, but if not it uses a close,
-but imperfect emulation. On such compilers:
-
-* Non-copyable objects can be stored in the containers.
-  They can be constructed in place using `emplace`, or if they support
-  Boost.Move, moved into place.
-* The containers themselves are not movable.
-* Argument forwarding is not perfect.
-
-__cb will use rvalues and move emulations for value types only if move constructor and move assignment operator of the value type do not throw;
-or if the value type has no copy constructor.
-
-Some methods won't use move constructor for the value type at all, if the constructor throws. This is 
-required for data consistency and avoidance of situations, when aftrer an exception __cb 
-contains moved away objects along with the good ones.
-
-See documentation for [@boost:libs/type_traits/doc/html/boost_typetraits/reference/is_copy_constructible.html `is_copy_constructible`], [@boost:libs/type_traits/doc/html/boost_typetraits/reference/is_nothrow_move_assignable.html `is_nothrow_move_assignable`] and [@boost:libs/type_traits/doc/html/boost_typetraits/reference/is_nothrow_move_constructible.html `is_nothrow_move_constructible`] type triats. 
-There you'll find information about how to make constructor of class noexcept and how to make a non-copyable 
-class in C++03 and C++98.
-
-Performance of __cb will *greatly improve* if value type has noexcept move constructor and noexcept move assignment.
-
-[h3 Exceptions of move_if_noexcept(T&)]
-
-Reference documentation of the __cb contains notes like "Throws: See Exceptions of `move_if_noexcept(T&)`".
-That note means the following: `move_if_noexcept(T& value)` does not throws exceptions at all, but it returns
-`value` as rvalue reference only if class `T` have noexcept move constructor and noexcept move assignment operator; 
-or if it has no copy constructor. Otherwise `move_if_noexcept(T& value)` returns `value` as const reference. 
-
-This leads us to the following situation:
-
-* If `value` has a noexcept move constructor and noexcept move assignment operator, then no exceptions will be thrown at all.
-* If `value` has a throwing move constructor and some copy constructor, then method may throw exceptions of copy constructor.
-* If `value` has no copy constructor, then method may throw exceptions of move constructor.
-
-`move_if_noexcept(T&)` uses [@boost:libs/move/index.html Boost.Move], [@boost:libs/type_traits/doc/html/boost_typetraits/reference/is_copy_constructible.html `is_copy_constructible`], [@boost:libs/type_traits/doc/html/boost_typetraits/reference/is_nothrow_move_assignable.html `is_nothrow_move_assignable`] and [@boost:libs/type_traits/doc/html/boost_typetraits/reference/is_nothrow_move_constructible.html `is_nothrow_move_constructible`] type triats. 
-
-
-[h3 Caveats]
-
-The __cb should not be used for storing pointers to dynamically allocated objects.
-When a circular buffer becomes full, further insertion will overwrite the stored pointers
-- resulting in a [*memory leak]. One recommend alternative is the use of smart pointers, for example
-[@http://www.boost.org/doc/libs/1_53_0/libs/smart_ptr/smart_ptr.htm Boost Smart pointers].
-
-[@http://en.wikipedia.org/wiki/Std::auto_ptr std::auto_ptr]
-
-[caution Any container of `std::auto_ptr` is considered particularly hazardous.]
-
-[tip Never create a circular buffer of `std::auto_ptr`.
-Refer to Scott Meyers' excellent book Effective STL for a detailed discussion.
-(Meyers S., Effective STL: 50 Specific Ways to Improve Your Use of the Standard Template Library.
-Addison-Wesley, 2001.)
-]
-
-While internals of a __cb are circular, [*iterators are not].
-Iterators of a __cb are only valid for the range `\[begin(), end()\]`,
-so for example: iterators `(begin() - 1)` and `(end() + 1)` are both invalid.
-
-[h3 Debug Support]
-
-In order to help a programmer to avoid and find common bugs,
-the __cb can be enabled to provide a kind of debug support.
-
-When the debugging functionality is enabled, the __cb maintains a list of valid iterators.
-As soon as any element gets destroyed all iterators pointing to this element
-are removed from this list and explicitly invalidated (an invalidation flag is set).
-The debug support also consists of many assertions (`BOOST_ASSERT` macros)
-which ensure the __cb and its iterators are used in the correct manner at runtime.
-In case an invalid iterator is used, the assertion will report an error.
-The connection of explicit iterator invalidation and assertions
-makes a very robust debug technique which catches most of the errors.
-
-Moreover, the uninitialized memory allocated by __cb is filled with the value `0xcc` in the debug mode.
-When debugging the code, this can help the programmer  to recognize the initialized memory from the uninitialized.
-For details refer the source code [@boost:boost/circular_buffer/debug.hpp circular_buffer/debug.hpp].
-
-[caution Since the debugging code makes __cb and its iterators more interconnected, thread safety guarantees of __cb
-are different when debug support is enabled. In addition to the container itself, all iterators tracked by the container
-(including any copies thereof) must be protected from concurrent access. In particular, this includes copying, destroying or
-obtaining iterators from the container, even if for read-only access.]
-
-The debug support is disabled by default. To enable it, one has to define `BOOST_CB_ENABLE_DEBUG` macro with the value of 1
-while compiling the code using __cb.
-
-[h3 Compatibility with Interprocess library]
-
-The __cb is compatible with the [@boost:libs/interprocess/index.html  Boost.Interprocess]
-[/ This should be in @boost:libs/interprocess/doc/index.html ]
-library used for interprocess communication.
-Considering that the circular_buffer's debug support relies on 'raw' pointers
-(which is not permited by the Interprocess library)
-the code has to compiled with debug support disabled (i.e. with `BOOST_CB_ENABLE_DEBUG` macro not defined or defined to 0).
-Not doing that will cause the compilation to fail.

-
-[import ../example/circular_buffer_sum_example.cpp]
-
-[circular_buffer_sum_example_1]
-
-[/circular_buffer_example_output - there is no output for this example]
-
-The __cb has a capacity of three `int`.
-Therefore, the size of the buffer will never exceed three.
-The `std::accumulate` algorithm evaluates the sum of the stored elements.
-The semantics of the __cb can be inferred from the assertions.
-
-You can see the full example code at [@boost:libs/circular_buffer/example/circular_buffer_sum_example.cpp  circular_buffer_sum_example.cpp].
-
-[h3 Bounded Buffer Example]
-
-The bounded buffer is normally used in a producer-consumer mode:
-producer threads produce items and store them in the container
-and consumer threads remove these items and process them.
-The bounded buffer has to guarantee that
-
-* producers do not insert items into the container when the container is full,
-* consumers do not try to remove items when the container is empty,
-* each produced item is consumed by exactly one consumer.
-
-[import ../example/circular_buffer_bound_example.cpp]
-
-[circular_buffer_bound_example_1]
-
-[/ there is no output for this example]
-
-The bounded_buffer relies on [@boost:/doc/html/thread.html Boost.Thread]
-and [@boost:libs/bind/index.html Boost.Bind] libraries
-and [@boost:libs/utility/call_traits.htm Boost.call_traits utility].
-
-The [memberref boost::circular_buffer::push_front() push_front()]
-method is called by the producer thread in order to insert a new item into the buffer.
-The method locks the mutex and waits until there is a space for the new item.
-(The mutex is unlocked during the waiting stage and has to be regained when the condition is met.)
-If there is a space in the buffer available,
-the execution continues and the method inserts the item at the end of the __cb.
-Then it increments the number of unread items and unlocks the mutex
-(in case an exception is thrown before the mutex is unlocked,
-the mutex is unlocked automatically by the destructor of the scoped_lock).
-At last the method notifies one of the consumer threads
-waiting for a new item to be inserted into the buffer.
-
-The [memberref boost::circular_buffer::pop_back() pop_back()]
-method is called by the consumer thread in order to read the next item from the buffer.
- The method locks the mutex and waits until there is an unread item in the buffer.
-If there is at least one unread item,
-the method decrements the number of unread items and reads the next item from the __cb.
-Then it unlocks the mutex and notifies one of the producer threads
-waiting for the buffer to free a space for the next item.
-
-The `bounded buffer::pop_back()`
-method [*does not remove the item] but the item is left
-in the circular_buffer which then [*replaces it with a new one]
-(inserted by a producer) when the circular_buffer is full.
-This technique is more effective than removing the item
-explicitly by calling the  [memberref boost::circular_buffer::pop_back() circular_buffer::pop_back()]
-method of the __cb.
-
-This claim is based on the assumption that an assignment (replacement)
-of a new item into an old one is more effective than a destruction
-(removal) of an old item and a consequent inplace construction (insertion) of a new item.
-
-For comparison of bounded buffers based on different containers compile and
-run [@boost:libs/circular_buffer/test/bounded_buffer_comparison.cpp bounded_buffer_comparison.cpp].
-The test should reveal the bounded buffer based on the __cb is most effective
-closely followed by the `std::deque` based bounded buffer.
-(In reality, the result may differ sometimes because the test
-is always affected by external factors such as immediate CPU load.)
-
-[import ../test/bounded_buffer_comparison.cpp]
-
-You can see the full test code at [@boost:libs/circular_buffer/test/bounded_buffer_comparison.cpp bounded_buffer_comparison.cpp],
-and an example of output is [bounded_buffer_comparison_output].

-
-Thomas Witt in 2002 produced a prototype called cyclic buffer.
-
-The circular_buffer has a short history. Its first version was a std::deque adaptor.
-This container was not very effective because of many reallocations when inserting/removing an element.
-Thomas Wenish did a review of this version and
-motivated me to create a circular buffer which allocates memory at once when created.
-
-The second version adapted `std::vector` but it has been abandoned soon
-because of limited control over iterator invalidation.
-The current version is a full-fledged STL compliant container.
-
-Pavel Vozenilek did a thorough review of this version and came with many good ideas and improvements.
-
-The idea of the space optimized circular buffer has been introduced by Pavel Vozenilek.
-
-Also, I would like to thank Howard Hinnant, Nigel Stewart and everyone
-who participated at the formal review for valuable comments and ideas.
-
-Paul A. Bristow refactored the documentation in 2013 to use the full power of Quickbook, Doxygen and Autoindexing.
