Comment (by tscrim):
I think you should do:
- `if self.base_ring() is R:` in `_element_constructor_` instead of the
`==`.
- Move the unshuffle out into `combinat/combinat.py` since it is a general
(low-level) operation.
- Is using the `remove_zeros` option the fastest, as opposed to doing the
`!= R.zero()` check (which probably should be pulled out?)
Otherwise your changes look good. For the interior product, I'm using the
definition I gave (the other one should be equivalent to the first one...)
with `\alpha` as `x`.
PS - John, I'm still working on the centers.
