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).
