Comment (by ghseeli):
I talked to my co-authors and we seem to agree that "PropogatingIdeal"
might be a better name for a few reasons:
1) There are actually many ideals in the PartitionAlgebra.[[BR]]
2) It is defined based on the propagating number of the diagrams.[[BR]]
3) It is technically a non-unital algebra, which makes calling it an
algebra debatable amongst some circles.
Once this is done, I think this enhancement is good to go.
Replying to [comment:9 tscrim]:
> Okay, here's my review patch. I changed `IdealAlgebra` to
`IdealPartitionAlgebra`, which is (much) better but I'm not perfectly
happy with. If you can think of a better name, then I'll change it. I've
also reorganized the class structure to better use base classes and
implemented a coercion up to the ambient space for the subalgebras. After
that it's mostly docstring/doctest additions and corrections.

> If you agree with my changes (and can't think of a better name), you can
go ahead and set this to positive review. Thanks.
