* Dont default the dim argument

* Implement argmin() and argmax() without dim
* Call .contiguous() before .view(-1)
This changes type(tensor) to return `torch.Tensor` instead of
`torch.autograd.Variable`.
This requires a few implementation changes:
- torch.Tensor is now a regular Python class instead of a
pseudo-factory like torch.FloatTensor/torch.DoubleTensor
- torch.autograd.Variable is just a shell with a __new__ function.
Since no instanes are constructed it doesn't have any methods.
- Adds torch.get_default_dtype() since torch.Tensor.dtype returns
<attribute 'dtype' of 'torch._C._TensorBase' objects>

Questions/possible future works:
How to template-ize to extend support beyond LongTensor?
How to check if autograd works (and if not, how to add explicit gradient)?
CUDA support?

This replaces the torch.Tensor constructors with factories that produce
Variables. Similarly, functions on the torch module (e.g. torch.randn)
now return Variables.
To keep the PR to a reasonable size, I've left most of the unused tensor
code. Subsequent PRs will remove the dead code, clean-up calls to
torch.autograd.Variable, and rename Variable to Tensor everywhere.
There are some breaking changes because Variable and Tensors had
slightly different semantics. There's a list of those changes here:
https://github.com/pytorch/pytorch/wiki/Breaking-Changes-from-Variable-and-Tensor-merge
* Various testing and utility improvements including torch.testing module.
1) Remove method definition for randn_like since ones_like, zeros_like do not have methods.
2) Add an empty_like native function for creating a tensor with uninitialized values.
3) Add an is_floating_point() native function, similar to is_signed().
4) Add a torch.testing module loosely modeled after numpy.testing; currently it contains
make_non_contiguous (moved from test_autograd) and randn_like (wrapper around the VariableFunction).
5) Remove code from test_autograd and test_nn that is responsible for generating grad_outputs to use
with gradgradcheck. These now use gradgradcheck's own generating code. This fixes
test_nn.py with scalars because gradgradcheck does the right thing here already.
* Rename parameter.
* Fix parameter usages.
This moves the implementation of repeat to _utils so that the autograd
function can call it directly instead of relying on forward being called
on tensors.
This also removes _range, which was previously necessary because we
shadowed the built-in range() function.
If the left tensor is 3D+ and the right tensor is at most 2D, we can
fold the batch into the matrix dimension and use torch.mm instead of
torch.bmm. In practice, this is faster especially if the right tensor is
column major.
* Add torch.matmul function.
Includes test_torch, test_autograd and docs changes.
* Add __all__ to functional so imports are accidentally imported.
* Include unbind in __all__.
* Add matmul case for when one argument is 1-dimensional and the other
at least 3-dimensional.
* Add squeeze_ to Variable.
* Use squeeze_ instead of squeeze for matmul.
This saves an extra memory copy, which speeds up data loading a bit
(5-10% with accimage).
As part of this change:
* torch.cat accepts keyword argument out
* sepcifiying out=None is treated like not specifying out
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.
