// Purpose: Define a buffer class to decouple the silicon geometer from the
//          geometry manager.  When a new geometry is required, the geometry
//          manager calls 
//
//             SiGeometerDecoupler::refresh(pointer_to_new_silicon_geometry)
//
//          and the implementation of refresh passes this on to the actual
//          silicon geometer.
