New description:
The attached patch implements methods for left and right matrix actions on
binary quadratic forms. It also extends the constructor {{{BinaryQF}}} to
accept a homogeneous polynomial of degree 2 in 2 variables.
I'm ccing other people who have worked on this file to see if anyone is up
for a quick review.

Comment:
I have implemented Gonzalo's suggestions. It seems to work great, and
indeed it's much faster; the matrix actions are almost 3 times faster with
the new code, and {{{__call__}}} is an amazing 200 times faster.
