Description (last modified by was)
It should have:
- simplify_* methods
- underlying data should be a pointer to a maxima matrix object, so that matrix operations are very fast.
This should also resolve a bug reported by Kate Minola on 20070914 with doctesting
sage -t devel/sage-main/sage/plot/plot3d/transform.pyx

I've posted a preliminary bundle. Something's up with the eigenvalues command however.
