Renderer-Exporters for IPython notebook files and 3d molecular structures.

Note that I added a templates folder under the root folder because that's where Flask seems to want to find html templates by default. Each module stores its templates under /templates/ \<module-name\>/

Renderer for IPython notebooks:
- It appears that one non-python dependency for IPython's notebook conversion library is [pandoc](http://johnmacfarlane.net/pandoc/). In a Heroku app I made, I got it to work by using a buildpack that fetches the pandoc binaries from:

https://www.strongspace.com/shared/lcblcx3vbt/pandoc.tar.gz
https://www.strongspace.com/shared/lcblcx3vbt/pandoc-templates.tar.gz

- It can export regular python scripts (with markdown cells commented out) or notebook json (ipynb) files. I'll look into incorporating some of the other export options that IPython's nbconvert module provides: e.g., latex, pdf, reveal.js presentation slides.

Renderer for PDB protein databank files:
- Uses GLMol.js (LGPL) and Three.js
