00062 Revision 1.1  2001/05/22 10:54:55  mpeeters
00063 Moved sources and headers for libModel to model/ subdirectory, in an attempt to rationalize the source tree. This should make things "netter".
00064 
00065 Revision 1.2  2000/09/15 10:26:31  mpeeters
00066 Cleaned out header and added CVS tails to files, removed superfuous
00067 @author comments, inserted dates
