FUNCTION: LieTools/BGGconditionA
USAGE: BGGconditionA(hfw,Gt); BGGconditionA(hfw); BGGconditionA(hfw,Gtype,rnk); 
SYNOPSIS: BGGconditionA(hw,Gt) finds the highest weights of Verma modules that
   are submodules of the Verma module with highest weight hfw (expressed in terms
   of a basis of fundamental weights);
EXAMPLE:
> with(LieTools):
> hfw := [-1/2,-1/2]:
> bgg := BGGconditionA(hfw,G2);

      bgg := [[3/2, 3/2], [-3/2, 5/2], [7/2, -1/2], [1/2, 1/2]]
