00080 Revision 1.1  2001/05/22 10:54:55  mpeeters
00081 Moved sources and headers for libModel to model/ subdirectory, in an attempt to rationalize the source tree. This should make things "netter".
00082 
00083 Revision 1.2  2000/09/15 10:26:31  mpeeters
00084 Cleaned out header and added CVS tails to files, removed superfuous
00085 @author comments, inserted dates
