Pull request: Separation of variables for PDEs

Hey! I have made the final documentation and code touches to my many variable separation trees, I have rebased and rewritten the history (only ) and now I consider it to be tree-ready :) Please pull from my github's 'variable-separation' branch. You can pull from git://github.com/plaes/sympy.gi

[PATCH] Move expand and friends from core.functions to simplify.expand

While trying to figure out the cause of bug #1527, I noticed some low-hanging stuff that could be easily fixed.. :) While looking around in sympy/core/function.py I noticed it contains bunch of extend*() functionality, which IMHO does not belong there. So I decided to move all these functions to
