New description:
A constellation is a combinatorial description (via elements of the
symmetric group) of graphs embedded in surfaces (also called G-map). This
ticket aims to implement a basic class for it with:
* fast data type
* normal form and isomorphism test
* enumeration/generation with constraints
Apply:
* trac_9806-constellations-vd.patch
* trac_9806-constellations-doc-patch-fc.patch

Comment (by vdelecroix):
Replying to [comment:7 chapoton]:
> Could you please upload the most recent constellation patch from the
sage-combinat queue ? It seems that the version there is not the same, and
my review patch does not apply ..
Done.
