- Fixed a few problems with hklscan

- Added transfer of zipped data to conman.c, histogram memory software
  in order to support the TRICS status display.
- Upgraded TRICS data file writing.
- First installment of triple axis spectrometer support: initialization of
  data structures and an implementation of the MAD dr(ive) command.
