Wrapper class for Sage sets as SymPy sets

[mkoeppe]

We add a _sympy_ method to all sets. It creates an instance of the new class sage.interfaces.sympy_wrapper.SageSet, which is a subclass of SymPy's Set class.

Here's a beginning. This obviously needs many more examples/tests

I know it is not so useful, but please add a doctest for __new__. Perhaps running a TestSuite? Other than that, LGTM assume a green bot.
