*
* $Log$
* Revision 1.1 2006/04/05 20:27:30 dhdfu
* A Great Reorganzation of header files and executables
*
* Revision 1.2 2006/02/23 05:07:53 arthchan2003
* Merged from branch SPHINX3_5_2_RCI_IRII_BRANCH: split whmm's routine.
*
* Revision 1.1.2.4 2005/09/07 23:40:06 arthchan2003
* Several Bug Fixes and Enhancements to the flat-lexicon
* 1, Fixed Dox-doc.
* 2, Add -worddumpef and -hmmdumpef in parrallel to -worddumpsf and
* -hmmdumpsf. Usage is trivial. a structure called fwd_dbg_t now wrapped
* up all these loose parameters. Methods of fwd_dbg are implemented.
* 3, word_ugprob is now initialized by init_word_ugprob
* 4, Full-triphone expansion is implemented. User can change this
* behavior by specifying -multiplex_multi and -multiplex_single. The
* former turn on multiplex triphone for word-begin for multi-phone word.
* The latter do that for single-phone word. Turning off both could
* tremendously increase computation.
* 5, Word expansions of possible right contexts now records independent
* history. The behavior in the past was to use only one history for a
* word.
*
* Revision 1.1.2.3 2005/07/24 01:42:58 arthchan2003
* Added whmm_alloc_light, that will by-pass and not use any internal list inside whmm.c
*
* Revision 1.1.2.2 2005/07/17 05:57:25 arthchan2003
* 1, Removed wid from the argument list of eval_*_whmm, 2, Allow allocation of whmm_alloc to be more flexible.
*
* Revision 1.1.2.1 2005/07/15 07:48:32 arthchan2003
* split the hmm (whmm_t) and context building process (ctxt_table_t) from the the flat_fwd.c
