//- Class:          CAVirtualVG
//- Owner:          Tim Tautges
//- Description:    Cubit attribute for virtual geometry entities
//-                 (holds both virtual vertices and virtual curves)
//- Checked by:
//- Version:
//-
//- This attribute stores:
//- numVV: number of virtual vertices
//- numVC: number of virtual curves
//- vgUIDs[0..numVV-1]: UID's of virtual vertices
//- vgUIDs[numVV..(end)]: for each curve, UID's of start, end vertices, then
//-                 UID of virtual curve
//- posVector[0..numVV-1]: position of virtual vertices
//- posVector[numVV..(end)]: positions of vpoints defining vcurve (not including ends)
//- numVCPoints: number of virtual points for each virtual curve
