FUNCTION: LieTools/MkDominant
USAGE: MkDominant(fwgt,Gt); MkDominant(fwgt); MkDominant(fwgt,Gtype,rnk);
SYNOPSIS: MkDominant(fwgt) will Weyl reflect a weight (expressed in terms of 
   a basis of fundamental weights) until it is dominant. Using MkDominant with
   a single argument fwgt requires a previously initialized global Lie algebra 
   environment (see LieTools[gSetup]).
EXAMPLE: 
> MkDominant([0,-1],G2);
                                [0, 1]
