--------------------------------------------------------------------------
   Check whether the supplied data structure is for circular geometry or not. 
   Note:   Not necessary in C++, as overloaded functions with different data 
           structure inputs will be used.

   Since version 7.

   Usage:
   a = IsCircGeom( geom );
