Comment (by darij):
Ready for review.
The `restriction_shape` method has been introduced in `tableau.py` because
it is at least twice faster than `restrict(i).shape()` (probably due to
the hackery with exceptions in the latter) and the shape of the
restriction seems to be used more often than the restriction itself. The
`restriction_outer_shape` method in `skew_tableau.py` is arguably less
useful (it is only about 20% faster than `restrict(i).outer_shape()` in
the cases I checked) and I will remove it if you think it clutters up
stuff.
Some of the doc bugs fixed here are due to me *oops*.
