Revision:	1402
Committed:	Fri Jan 8 17:15:27 2010 UTC (15 years, 9 months ago) by chuckv
File size:	5332 byte(s)
Log Message:	Added preliminary code for Alpha Hull calculation using qhull. Added preliminary support to SMIPD to support Alpha Hull. Alpha Hull does not yet add the correct things to triangle to be returned to SMPID. Preliminary changes for shadow hamiltonian integrator. Chages to md files so they will work in openMD.
