In the paper Similarity of matrices over local rings of length two
[http://arxiv.org/abs/1212.6157], the similarity classes of n x n matrices
with entries in a principal ideal local ring of length two are computed
for n = 2, 3, 4. These calculations are being implemented in sage.

Comment (by tscrim):
Hey Amri,
Here's a review patch which does a few things:
- Changes the name of the functions `*2` to `*_length_two` to be a little
more explicit.
- Adds `INPUT:` blocks to some of the functions.
- Fixes some docstring mistakes I didn't catch the first time around in
the whole file. I also converted it to use Sage's macro for finite fields
`\GF{q}`.
If you're happy with my changes, go ahead and set this to positive review.
Thanks for your work on this,[[BR]]
Travis
