CLIMATE-539 Get OCW on to PyPI

Hi Folks,
Pretty trivial update as an attempt to get us on to PyPI.
A couple of things here
 * I registered the 'ocw' package on testpypi [here](https://testpypi.python.org/pypi/ocw/0.5), the markdown is a disgrace so we need to work towards a solution for that as it is not displaying nicely on this mock up at all!!!
 *  We should probably consider adding to the README to include directions for how to install ocw via pip or easy_install e.g.
```
Installation
============

What follows are the installation instructions for Apache Open Climate Workbench.


Quick Instructions
------------------

As a user with administrative privileges, run either::

    pip ocw

or::

    easy_install ocw

depending on what's available on your system.  You're done!


Full Instructions
-----------------
... blah blah blah usual README.md
```
wdyt folks?
Hopefully this will make it much easier for people to build applications on top of the OCW toolkit.
