7fe0cb43a3 Change the definition of Doppler Spread (option "-d x" used in jt65sim
so that specified spreads correspond to the full limb-to-limb spread 
for EME.  Line widths at -3 dB will be 1/3 of the specified value.

507e318193 Many changes in aid of decoding signals with significant Doppler spread
in submodes JT65B, C.  More changes still to come!

0522f94d0b Change Doppler spread to Lorentzian shape with cutoff at x=3. Several
tweaks to output format from fer65.

2451639753 Change the definition of "d" so that width of generated tones is equal
to the requested Doppler spread.  Previously they were wider by the 
factor 2*sqrt(log(2)).

a7c6f42ba4 Many changes to the JT65 decode chain. This is development code! It
includes an initial implementation of the FTRSD decoder with a "qual"
parameter for evaluation of candidate codewords.  Also includes hinted
decoding.  Further testing is needed.

e4ad28fb92 Tidy up command line processing in Fortran tools
Build script now  builds jt65. The tools jt65 and  jt65sim usilize the
options module for all comamnd line parsing.

The  tool  jt65sim  now  has  conventinal  command  line  options  and
switchs. Default values have been  added where appropriate and options
documentation  updated. An  option to  disable PRNG  seeding has  been
added.

6bf40a28d7 Increase the JT65 range of acceptable DT: now -2 to +5 s. Note that
displayed DT values appear to be to low by 0.2 s -- they range from
-2.2 s to +4.8 s, according to files generated by jt65sim.
