 Purpose : base class for all kind of resources. "normal" machines
           are derived from this class. passive machines cannot
           process jobs, but in all other respects they are identical
           to "normal" machines

 Revision 1.14  1999/10/29 10:46:42  schickin
 line topology (between mesh and single-top.) added

 Revision 1.13  1999/10/27 12:57:33  schickin

 purpose of important classes noted in the header-files

 Revision 1.10  1999/06/17 16:34:37  hall
 STopology changed, tuned STSysSchedEvent-stuff and lost more!

 Revision 1.9  1999/04/27 13:39:30  schickin
 well folks, that's the first demo version that really runs 8-)

 Revision 1.8  1999/04/23  15:31:24  schickin
 sync with sunhalle

 Revision 1.7  1999/03/25 14:12:48  schickin
