FUNCTION: LieTools/MultsWgts
USAGE: MultsWgts(hfw,Gt); MultsWgts(hfw); MultsWgts[hfw,Gtype,rnk);
SYNOPSIS: MultsWgts(hfw,Gt) yields a list [wmults,fws] in which fws is a 
  list of the weights (w.r.t. our basis of of fundamental weights) of 
  the irreducible finite dimensional representation of Gt with highest 
  weight hfw, and wmults is a list of the multiplicities of these weights
  in the same representation; correlated so that 
         wmults[i] := multiplicity of fws[i] .
  When called with a singel argument hfw it is necessary to first initialize
  a global Lie algebra environment (see LieTools[gSetup]).
EXAMPLE: 
LieTools[MultsWgts]([0,1],G2);
  [[1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2], [[0, 1], [3, -1], [-3, 2],

        [3, -2], [-3, 1], [0, -1], [1, 0], [-1, 1], [2, -1], [-2, 1],

        [1, -1], [-1, 0], [0, 0]]]
