FUNCTION: LieTools/WgtMult
USAGE: WgtMult(fw,hfw,Gt); WgtMult(fw,hfw); WgtMult(fw,hfw,Gtype,rnk);
SYNOPSIS: WgtMult(fw,hfw,Gt) returns the multiplicity of the fw-weight space 
  in the irreducible finite dimensional representation of Gt with highest weight
  hfw. (All weights are to be expressed relative to a basis of fundamental weights.)
  When called with just two arguments fw and hfw, it is necessary to first 
  initialize global Lie algebra environment (see LieTools[gSetup]).
EXAMPLE: 
> with(LieTools):

> WgtMult([0,0],[1,1],A2);

                                  2
