Title: WIP Isotonic regression

Here is a PR for a new isotonic regression, replacing the one in the manifold's mds implementation. It has now a proper sklearn interface, with a fit method.
The isotonic regression code now implements weights, and a couple of extra options. (Fabian and Alex actually implemented this version of the code, so it is necessarily perfect.) The MDS code has been updated to use this new version.

There's still the documentation to work on, and a small example.
