New description:
The Tamari poset is a partial order on planar binary trees or Dyck paths.
(see [http://en.wikipedia.org/wiki/Tamari_lattice Tamari Lattice] in
Wikipedia)
It has been generalized recently by F. Bergeron and his collaborators.
The patch below implements these posets, and even more general versions.
