00056 Revision 1.1  2001/05/22 10:54:55  mpeeters
00057 Moved sources and headers for libModel to model/ subdirectory, in an attempt to rationalize the source tree. This should make things "netter".
00058 
00059 Revision 1.2  2000/09/15 10:26:31  mpeeters
00060 Cleaned out header and added CVS tails to files, removed superfuous
00061 @author comments, inserted dates
