Title: first draft of SymPyCCode op

```Python
class SymPyCCode(ScalarOp):
""" An Operator that wraps SymPy's C code generation

>>> from sympy.abc import x, y # SymPy Variables
>>> from theano.scalar.basic_sympy import SymPyCCode
>>> op = SymPyCCode([x, y], x + y)

>>> from theano.scalar.basic import floats
>>> xt, yt = floats('xy') # Theano variables
>>> zt = op(xt, yt)

>>> import theano
>>> f = theano.function([xt, yt], zt)
>>> f(1.0, 2.0)
3.0
