  Merged RTF class documentation into headerdoc comments


  10/12/89/daj - Created.
  11/12/89/daj - Added _MKClassSamples() and _MKClassPartials().
  11/22/89/daj - Added _MKGetEnvelopeNth().
  11/26/89/daj - Added _MKBeginUGBlock() and _MKEndUGBlock().
  3/7/93/daj - Moved somet things from _unitGeneratorInclude.h to here.
  3/7/93/daj - Added tracing support
  2/26/94/daj - Got rid of _MKUGLog2
