New description:
This patch adds documentation to some rowmotion-related methods in
{{{sage/categories/posets.py}}} and {{{sage/categories/finite_posets.py}}}
and introduces new methods which return iterators over single rowmotion /
Panyushev complementation / toggle orbits instead of computing *all*
orbits at once and returning them as lists. This allows experimenting with
big posets (at least if one can find a way to more or less randomly sample
order ideals or antichains).

Comment:
OK, Nathann is right, this ticket should be split:
for the '''patchbots''':
apply trac_15283-rowmotion-dg.patch
for the '''patchbot''':
apply trac_15283-rowmotion-dg.patch
for the '''patchbots'''
apply trac_15283-rowmotion-dg.patch
for the '''patchbot'''
apply trac_15283-rowmotion-dg.patch
This can then be set to positive_review since Nathann did review the
rowmotion patch.
