Title: WIP: diffusion map embedding

this is a very early PR for diffusion map embedding into scikits-learn (started incorporating the basic matrix functions).

i would really like some advice as to where this should go:

it seems it could go with affinity_propagation as a pure matrix based method or it could go with the manifold learning (which is where it is now)
