FUNCTION: LieTools/TensorProduct
USAGE:  TensorProduct(fw1,fw2,Gt); TensorProduct(fw1,fw2); 
        TensorProduct(fw1,fw2,Gtype,rnk);
SYNOPSIS: TensorProduct(fw1,fw2,Gt) uses Klimyk's formula (A.U. Klimyk, 
  Am. Math. Soc. Translations, 76, 63-73, (1968)) to compute the decomposition
  of the tensor product of finite dimensional representations with highest weights
  fw1 and fw2 (with respect to a basis of fundamental weights) into a direct sum of
  irreducible representations (with multiplicities).  When called with just two 
  arguments fw1 and fw2, it is necessary to first initialize a global Lie algebra
  environment (see LieTools[gSetup]).
