Make Variables not subclass Function anymore
...
Because of this Variables can no longer appear in the graph.
Every usage of a leaf Variable will leave an AccumulateGrad
function that has no outputs, but modifies var.grad as a side
effect.

Prevent creation of reference cycles with leaf Variables that don't require grad
...
Also, raise an error immediately, if a leaf that requiers_grad is
modified in-place. Some comments were updated too.

Refactor autograd package to separate Python dependencies. ( #662 )
...
The core autograd Variable, Function, and Engine no longer depend on the
Python API. This let's us implement functions in C++. In the future, we
can also multithread engine and release the GIL for most of the
non-Python backwards.
