FUNCTION: LieTools/UnBasis2PBWBasisFDR
USAGE: UnBasis2PBWbasisFDR(Unb,hwv);
SYNOPSIS: UnBasis2PBWbasisFDR(Unb,hwv) will produce a polynomial basis 
  the submdoule of U[g] generated by a highest weight vector
  hwv in U[g]. The parameter is a list of sequences of
  negative simple roots, whose application to the hwv should
  produce a basis for the representation of g generated from
  hwv.
CAVEATS: requires a previously initialized global Lie algebra environment.
