FUNCTION: LieTools/UgMonoWgt
USAGE: UgMonoWgt(umono); 
SYNOPSIS: UgMonoWght(umono) determines the weight of a monomial umono in U[g], 
  expressed in terms of a basis of simple weights
CAVEATS: requires a previously initialized global Lie algebra environment.
  (See LieTools[gSetup].)
EXAMPLE: 
> with(LieTools):gSetup(G,2):
Setting up Gtype = G   rnk = 2
> UgMonoWgt(u(g[1],g[1]));
