Interactive Binder Tutorial

[AVajpayeeJr]

This PR is intended to address #448. It includes the following changes -

• An IPython notebook giving a basic run-through of SKLL command line tools, utility scripts and Python API for IRIS classification task.
• Changes to README to include Binder launch logo and link to hosted notebook.

Notes - The interactive tutorial is meant to be done in conjunction with reading the SKLL documentation

Post-review, I shall change the link to point to master repository.

I think one comment I have is that we should create an ETS level account for binder rather than using @AVajpayeeJr 's personal account. I can take care of that as part of my review for this PR once I finish the PR I am working on.

[desilinguist]

I would like to make some changes to the notebook and that's much easier with a local branch rather than a branch on a fork. @AVajpayeeJr I have made a local branch containing your changes and will make another PR using that branch. So, I am going to close this PR.
