New description:
More support for finite dimensional modules and algebras with basis:
* Echelon form of list of vectors
* Submodules and quotients
* Example of a finite dimensional algebra with basis:
the path algebra of the Kronecker quiver
* Category SemisimpleAlgebras(...)
* Finite group algebras are semisimple in characteristic 0
* Center, radical, and semisimple quotient of a finite dimensional algebra
* Annihilator
* Matrix and inverse of module morphisms
* Some more support for term orders in CombinatorialFreeModule
* map_support_skip_none in ModulesWithBasis
The patch under development on the Sage-Combinat queue is close to
completion
