********>Bugfix 10:
Authors:  Terry Lang
Date:  July 22, 2005

Program:  nchemgrid_SA

Description:  One of the variables in nchemgrid.f is not initialized in the code and 
therefore does not run properly on Mac OS X platforms.  The nchemgrid_SA executable completes, 
but DOCK cannot process the bmp grid properly and the calculation seg faults.

Fix:  Make the following changes to the file utilities/GBSA_Grids/schemgrid_SA/nchemgrid.f.
