Revision:	1710
Committed:	Fri May 18 21:44:02 2012 UTC (12 years, 11 months ago) by gezelter
File size:	4477 byte(s)
Log Message:	Added an adapter layer between the AtomType and the rest of the code to handle the bolt-on capabilities of new types. Fixed a long-standing bug in how storageLayout was being set to the maximum possible value. Started to add infrastructure for Polarizable and fluc-Q calculations.
