00051  * $Log$
00052  * Revision 1.1  2006/04/05  20:27:30  dhdfu
00053  * A Great Reorganzation of header files and executables
00054  * 
00055  * Revision 1.2  2006/02/23 05:07:53  arthchan2003
00056  * Merged from branch SPHINX3_5_2_RCI_IRII_BRANCH: split whmm's routine.
00057  *
00058  * Revision 1.1.2.4  2005/09/07 23:40:06  arthchan2003
00059  * Several Bug Fixes and Enhancements to the flat-lexicon
00060  * 1, Fixed Dox-doc.
00061  * 2, Add -worddumpef and -hmmdumpef in parrallel to -worddumpsf and
00062  * -hmmdumpsf. Usage is trivial. a structure called fwd_dbg_t now wrapped
00063  * up all these loose parameters.  Methods of fwd_dbg are implemented.
00064  * 3, word_ugprob is now initialized by init_word_ugprob
00065  * 4, Full-triphone expansion is implemented. User can change this
00066  * behavior by specifying -multiplex_multi and -multiplex_single. The
00067  * former turn on multiplex triphone for word-begin for multi-phone word.
00068  * The latter do that for single-phone word. Turning off both could
00069  * tremendously increase computation.
00070  * 5, Word expansions of possible right contexts now records independent
00071  * history.  The behavior in the past was to use only one history for a
00072  * word.
00073  *
00074  * Revision 1.1.2.3  2005/07/24 01:42:58  arthchan2003
00075  * Added whmm_alloc_light, that will by-pass and not use any internal list inside whmm.c
00076  *
00077  * Revision 1.1.2.2  2005/07/17 05:57:25  arthchan2003
00078  * 1, Removed wid from the argument list of eval_*_whmm, 2, Allow  allocation of whmm_alloc to be more flexible.
00079  *
00080  * Revision 1.1.2.1  2005/07/15 07:48:32  arthchan2003
00081  * split the hmm (whmm_t) and context building process (ctxt_table_t) from the the flat_fwd.c
