 CurveType SYMBDPROD( CurveType Crv1, CurveType Crv2 )

 or

 SurfaceType SYMBDPROD( SurfaceType Srf1, SurfaceType Srf2 )

Computes the symbolic dot (inner) product of the given two curves or surfaces
as a scalar curve or surface.

Example:

 DiffCrv = symbdiff( Crv1, Crv2 )
 DistSqrCrv = SYMBDPROD( DiffCrv, DiffCrv )

Computes a scalar curve that at parameter t is equal to the distance
square between Crv1 at t and Crv2.
