The actual initial commit. Basic functionality works. Use the enclosed html file to test.

Things to do:
- Refactor so a "JSON to Chart" function does the work (it more flexible)
- Deal with font size nonsense think about benefits/costs of having a single font parameter and multiple parameters for multiple text types (maybe use objects... and make a verifyFont function...)
- Document it... Need a read me.md

Things to note:
- MathJax must run after embedded JSON to D3 text is parsed (hence the ugliness in init() in example.html)
