Title: Cup products on Ext modules
Description:
An M2 package computing the cup product maps Ext^i(M,M) x Ext^j(M,M) ->
Ext^(i+j)(M,M) where the module M is given by its presentation matrix. This
involves computing the min free resolution for M so might not be very effective
if the number of vars is large, but would allow some M2 users to play with
deformation theory.
--mike: this would be a nice one to do.
