New Revision: 4495

Modified:
   cgm/branches/merge-cubit12/geom/OCC/OCCLoop.cpp
   cgm/branches/merge-cubit12/geom/OCC/OCCLoop.hpp
   cgm/branches/merge-cubit12/geom/OCC/OCCModifyEngine.cpp
   cgm/branches/merge-cubit12/geom/OCC/OCCModifyEngine.hpp
Log:
Added split_curve function for merge_cubit12 specific requirement.
Added update_OCC_entity function in OCCLoop for split curve operation.
Added  a check for clean_up_slivers opetion for split_body with vectors.
Consolidate function split_shape_by_location for both split body and split curve funtions
