outerproduct_schur

synopsis: INT outerproduct_schur(OP parta,partb,result)

description:

you enter two PARTITION objects, and the result is a SCHUR object, which is the expansion of the product of the two schurfunctions, labbeled by the two PARTITION objects parta and partb. Of course this can also be interpreted as the decomposition of the outer tensor product of two irreducibe representations of the symmetric group.
