----------------------------+---------------------------------
As discussed on sage-devel [1], the two function `Graph.to_partition` and
`Poset.to_graph` do not have a very meaningful name.
As `Poset.to_graph` can be obtained from the clearer alternatives
`Graph(Poset.hasse_diagram())` or `Poset.hasse_diagram().to_undirected()`
it is not a problem to remove it. On the other hand, the discussion on
sage-devel seemed to indicate that `Graph.to_partition` should be renamed
rather than removed.
Also, as it appeared that people were more interested in the size of
connected components than in the actual `Partition` object, the new
function will only return a list of integers.
