mathjax for github.io site

For the project website hosted at http://allofphysicsgraph.github.io/proofofconcept/ I've been using static PNGs generated off-line to render the expressions in the graph using d3js.

In order to dynamically enter content on a webpage without resorting to off-line rendering, I used MathJax to display content.

The javascript for MathJax is at
https://github.com/mathjax/MathJax/blob/master/MathJax.js
with instructions for use here
https://docs.mathjax.org/en/latest/configuration.html

I was able to get a page that accepts input and renders Latex input:
http://allofphysicsgraph.github.io/proofofconcept/site/mjtest
Source code for the page is here:
https://github.com/allofphysicsgraph/proofofconcept/blob/gh-pages/site/mjtest.html

Next I ran scaling tests for latency as a function of the number of rendered expressions in Chrome.

25 expressions:

• http://allofphysicsgraph.github.io/proofofconcept/site/mjtest_scaling_25
• DOMContentLoaded: 203 ms; Load: 516 ms; Finish: 835 ms

50 expressions:

• http://allofphysicsgraph.github.io/proofofconcept/site/mjtest_scaling_50
• DOMContentLoaded: 202 ms; Load: 548 ms; Finish: 977 ms

100 expressions:

• http://allofphysicsgraph.github.io/proofofconcept/site/mjtest_scaling_100
• DOMContentLoaded: 220 ms; Load: 538 ms; Finish: 1140 ms
