All devices are equal! (#196)
* Update all devices to be tested

ANE, CPU and OCL all now support all tests.

However tests are not currently passing on GPU and I cannot test on CPU.

Failing GPU test are not an issue caused by this update. Tests have not
been passing due to a missing "six" required installation.

OpenCL Tests have not been run since commit: 1a1c63a08b

devices have 3 types and are handle by a new DeviceTypes enum. (The goal
is to revert to Tensor.<type>, but this current setup allows for keyword
argument defaults: `device=DeviceType.CPU`)

All references to Tensor.GPU/CPU/ANE as been converted to the
corresponding `DeviceTypes` enum.

Refactor of the conversion code to allow for any device to any device
conversion.

* Add six dependency in requirements.txt

* Resolve failure to run tests

Move six into gpu required installs. Remove six from standard
installation.

* Remove repeated data conversion

* Refactor method names

Also reduce code with .to and .to_

* Dynamic device handlers

* Refactor DeviceTypes -> Device

* Add mem copy profiling back

* test_backward_pass_diamond_model passing

* Resolve Sum issue on GPU

* Revert batchnorm2d tests

* Update README with upadated API

* ANE testing with

* Last minute line gains
