6336300880 Fix bug where adding a hook could replace an existing hook. 
We were keying hooks by RemovableHandle id. However, we don't hold onto
handles and ids of dead objects can be reused. This replaces id(handle)
with a global counter.

bd5303010d 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.

e7c1e6a8e3 [pep8] Fix most lint automatically with autopep8 
Here's the command I used to invoke autopep8 (in parallel!):

    git ls-files | grep '\.py$' | xargs -n1 -P`nproc` autopep8 -i

Several rules are ignored in setup.cfg. The goal is to let autopep8
handle everything which it can handle safely, and to disable any rules
which are tricky or controversial to address. We may want to come back
and re-enable some of these rules later, but I'm trying to make this
patch as safe as possible.

Also configures flake8 to match pep8's behavior.

Also configures TravisCI to check the whole project for lint.

7e4ddcfe8a Remove names from register_hook calls (#446) 
The register hook calls now return an object that can be used to remove
the hook. For example,

   >>> h = module.register_forward_hook(callback)
   >>> h.remove()  # removes hook

Or as a context manager:

   >>> with module.register_forward_hook(callback):
   ...     pass

This makes it easier for libraries to use hooks without worrying about
name collisions.

f2d7e94948 Use torch.Size for Tensor sizes and tuple for strides 
See issue #20

The torch.Size class is a tuple subclass which distinguishes sizes from
other tuples so that torch.Tensor(size) is interpreted as size instead
of data.

980300b381 Combine autograd.Leaf and autograd.Variable (#52) 
Prior to this change, there was a circular reference between Leaf and
Variable. This means that the objects (and referenced Tensors) are not
collected as soon as they go out of scope, which lead to higher memory
usage and out-of-memory errors.
