Make library into a distributable Python package.

[emanlove]

Initial version of the setup.py file to make this a package. This needs a review of values I have given to Author, Short Description, etc. and some additional information, like author's email.

One can install this package as source locally and continue developement using,

pip install -e </path/to/root/directory>

or simply install the package using pip install </path/to/root/directory>

I am looking into installing both the library src and the examples. I would suspect that, at least initially, people would want the example directory so they thry out the library using those demos examples.
