Comment (by cnassau):
Here's a new patch. This implements a {{{__ne__}}} on the
{{{AbstractFamily}}} base class and uses {{{SymmetricGroups}}} in place of
{{{Permutations}}} in the disjoint union doctests.
Actually, it wasn' easy to find an example of a Family where the pickling
tests worked smoothly: {{{Simplex}}} failed ({{{Simplex(n)}}} is not a
set), {{{GF}}} failed (elements not disjoint because of a common {{{0}}}),
{{{Subsets}}} failed (same defect as the original {{{Partitions}}}
example)...
Cheers,\\
Christian
