(gh-20) Added setup.py and new filesytem structure

## Added setup.py
The filesytem structure needed to be changed to something setup.py likes.

The project can now be registered with PyPi
```python
python setup.py register
```
And then uploaded 
```python
python setup.py sdist upload
```
Tests can be run from setup.py as well
```python
python setup.py nosetests
```

    * `README.md`
    * `setup.py`
