// Class FrequencyList
//
// Encapsulates a collection of frequencies. The implementation is a
// table containing the list of Frequency type elements which is
// editable and a second column which is an immutable double
// representation of the corresponding Frequency item scaled to
// mega-Hertz.
//
// The list is ordered.
//
// Responsibilities
//
// Stores internally a list of unique frequencies. Provides methods
// to add and delete list elements.
//
// Collaborations
//
// Implements the QSortFilterProxyModel interface for a list of spot
// frequencies.
