2ipython compatability module for nvd3-python 

3This adds simple ipython compatibility to the nvd3-python package, without making any 

4major modifications to how the main package is structured. It utilizes the IPython 

5display-formatter functionality, as described at: 

6http://nbviewer.ipython.org/github/ipython/ipython/blob/master/examples/notebooks/Custom%20Display%20Logic.ipynb
