FUNCTION: LieTools/DomChar
USAGE:  DomChar(hfw,Gt); DomChar(hfw); DomChar(hfw,Gtype,rnk);
SYNOPSIS: DomChar(hfw,Gt) will yield the dominant part of the character expansion
  of a finite dimensional representation with highest weight hfw (expressed in
  terms of list of its components with respect to the basis of fundamental weights). 
  When called with a single argument, hfw, it is necessary to first initialize the
  global Lie algebra environment via a call to LieTools[gSetup].
EXAMPLE: 
> LieTools[DomChar]([2,2],A2);

         X[2, 2] + X[0, 3] + X[3, 0] + 2 X[1, 1] + 3 X[0, 0]
