FUNCTION: LieTools/SgMkZeroWgtBasis
USAGE: SgMkZeroWgtBasisFDR(n,hfwgt);
SYNOPSIS: SgMkZeroWgtBasis(n,hfwgt) will construct a basis for the zero weights
  of a finite dimensional representation with highest weight hfwgt in
  the space of harmonic, homogeneous polynomials of degree n.
CAVEATS: requires a previously initialized global Lie algebra environment.
  (See LieTools[gSetup].)
EXAMPLE: 
> with(LieTools):
> gSetup(G,2):
Setting up Gtype = G   rnk = 2
> SgMkRepZeroWgtBasis([2,0],2);
