00072 Revision 1.1  2001/05/22 10:54:55  mpeeters
00073 Moved sources and headers for libModel to model/ subdirectory, in an attempt to rationalize the source tree. This should make things "netter".
00074 
00075 Revision 1.2  2000/09/15 10:26:31  mpeeters
00076 Cleaned out header and added CVS tails to files, removed superfuous
00077 @author comments, inserted dates
