Revision:	1725
Committed:	Sat May 26 18:13:43 2012 UTC (12 years, 11 months ago) by gezelter
File size:	5205 byte(s)
Log Message:	Individual ForceField classes have been removed (they were essentially all duplicates anyway). ForceField has moved to brains, and since only one force field is in play at any time, the ForceFieldFactory and Register methods have been removed.
