This would be good for someone who wants to learn the underlying (advanced) theory.
See the preliminary code in BGG.m2.
See also the code on Frank Schreyer's web site
(http://math.uni-sb.de/ag-schreyer/home/computeralgebra.htm) in
computingRpi_star.m2 associated with math.AG/0506391, which implements the
algorithm, but it needs to be put into a package form, with a general
interface.
