 * HISTORY
 * $Log: glist.h,v $
 * Revision 1.9  2005/06/22 03:02:51  arthchan2003
 * 1, Fixed doxygen documentation, 2, add  keyword.
 *
 * Revision 1.4  2005/05/03 04:09:11  archan
 * Implemented the heart of word copy search. For every ci-phone, every word end, a tree will be allocated to preserve its pathscore.  This is different from 3.5 or below, only the best score for a particular ci-phone, regardless of the word-ends will be preserved at every frame.  The graph propagation will not collect unused word tree at this point. srch_WST_propagate_wd_lv2 is also as the most stupid in the century.  But well, after all, everything needs a start.  I will then really get the results from the search and see how it looks.
 *
 * Revision 1.3  2005/03/30 01:22:48  archan
 * Fixed mistakes in last updates. Add
