todo list, with priority order : (following somehow the doxygen todo's
tags)



STICKY * always make functionality exhaustive and randomised tests.

* implement denses matrices over a ring and over a field. With respect to the fact that
the ring is an integral domain (so maybe working on the fractions field if
faster algorithms are possible) or not. With respect to the fact that the ring
is isomorphic to a computable cartesian product of fields or not (for example
Z/nZ is isomorphic to Z/pZ times Z/qZ when n = pq, p and q primes ; but use this
only when the factorization of n is known or easy to compute...)

* implement product ring (the cartesian product of rings is a ring)

* implement generic fractions field
