Make the RMTK library installable

[daniviga]

• Fixes a clash in the python package name since an __init__.py was existing in the repo top level folder (which is and should not be a python package)
• Makes the RMTK (just the python package not the notebooks) installable using pip install [-e] or python setup.py, so the notebook can run without having to set manually the PYTHONPATH which was causing confusion to users (also due the issue above)
• Move the ipython notebook out from the python package. They are not python code/packages and cannot be installed. They are run (from RMTK.ipynb) as usual from the repo location

TODO

• We still need to track the dependencies and add them to the setup.py (with a proper version range)
• Update README

How it works now

virtualenv foo
source ~/foo/bin/activate

git clone https://github.com/GEMScienceTools/rmtk.git
cd rmtk
# install the rmtk library
pip install -e rmtk
# install ipython and run the notebooks
pip install jupyter ipython notebook
jupyter notebook
