Comment (by rohana):
I noticed a a flaw with what I did -- `ConwayPolynomials()[p]` returns a
mutable Python dict, so you can actually write to the database. I'll post
a fix for this in a moment.
There is no good reason as far as I can tell to use anything but plain
text in the SPKG considering how small the database is.
As for the second question, the only concern would be that the entire
database is loaded into memory with each instance (granted this might not
be a huge concern due to the small size of the database). The main reason
I added the inheritance of `UniqueRepresentation` was because of a comment
I seem to recall being told that Sage databases should be unique. It is
simple enough to remove if we deem it not necessary.
