New Revision: 4918

Modified:
   cgm/trunk/itaps/iGeom.h
   cgm/trunk/itaps/iGeom_CGMA.cc
Log:
Add documentation to interface for getFacets method.

Assign values to return variables that indicate size of allocated space.

Passes make check - although there are not yet any tests for this method anyway!
