Add back the drop_dependent() function.

It turns out that it doesn't matter if our basis is orthogonal, so we
don't need to do Gram-Schmidt. Since this will be relied upon in the
paper, we go back to using (a subset of) the rays of the cone as our
basis.

Everything's still a mess, but at least the tests are passing. No more
do we check for exact equality between K_W and K_star_W_star; instead
we just check that many properties agree. In the paper we have an
isomorphism, and equality holds. However, my isomorphism isn't an
isomorphism when using a coordinate system -- and we have to use a
non-normal one in Sage because we can't normalize vectors over
QQ. Huh.
