// .NAME vtkMergeOperation - Merge a set of geometric model entities
// .SECTION Description
// Operation to merge a set of source geometric model entities into
// a target geometric entity on the server.  The properties of the target entity
// (e.g. color, BCS/ModelEntityGroup associations) will not be changed.
// Warning: This may only currently work from model faces.
