SchurComplexes -- Schur functors of chain complexes

Description

This package computes the Schur complex $S_{\lambda}F_{\bullet}$ associated to a bounded chain complex $F_{\bullet}$ of finitely-generated free modules, and a partition $\lambda$. Our conventions are the transpose of the convention in "Cohomology of Vector Bundles and Syzygies", by Jerzy Weyman, Chapter 2.4.
