Comment:
Let `C` be a linear code with `H` a parity check matrix of `C`. The
generator matrix of `C`'s dual is `H`. I made changes in
`AbstractLinearCode`'s `dual_code` method to use that property instead of
the old implementation and got something faster.
I also rewrote `AbstractLinearCode`'s `__eq__` which is now less heavy and
a bit faster.
Finally, I removed a lot of old debug prints that were still present in
this file as commented lines.
This is now ready for review.
