Add PyTorch support in Pipeline class

[juneoh]

This is a re-post of pull request #45. Build failure is now fixed, but .travis.yml became messy, for:

• torchvision is not on PyPI, only on Anaconda
• torchvision supports only Python 2.7, 3.5, and 3.6

That's real nice work with this new PR!

[juneoh]

Thanks for the quick merge! Now I'll be able to persuade my colleagues to use this.

Nice! Spread the word :-)
PS because this is quite a nice feature to have, I will update Augmentor to version 0.1.6 and put that version on the PyPI, so that current installs will get updated by pip (and of course will be included in any new installs).

OK so this is now done, @juneoh . Your PR is part of version 0.1.6 (now live on PyPI) and the README.md has also been updated to reflect the ability to use Augmentor with PyTorch. Thanks again for the input!

Wow, it must be Christmas already! I’ll share the good news with the PyTorch community in my neighborhood. Thanks so much :)
