Summary:
Add checks in the makefile to not run mac-only things when not on a
mac. (I've only tested on linux, I haven't ensured that this runs mac-only
things on a mac)
Test Plan:
- Run `make`
- Have it not break

Summary:
This commit adds an HTML file for creating perceptual diffs (pdiff.html),
a reference screenshot of that HTML file (pdiff.png), and a quick script
for comparing that screenshot to a newly generated one (pdiff.js).
Also added a basic README.
Test Plan: make pdiff

Summary:
This diff does a couple different things:
- There is now a metrics/ folder, which contains the property files describing
the metrics if the fonts, as well as a script for reading and printing the
metrics in javascript.
- Fractions and superscripts/subscripts are now rendered in slightly different
ways now (notably, no use of inline-table). This allows for much more precise
positioning of the superscripts, subscripts, numerators, and denominators,
while still having an appropriate baseline. Also, there is no longer a
sup/sub/supsub distinction, there are only supsubs with null sup/sub.
- Using the new font metrics and by implementing the formulas found in The TeX
Book, Appendix G, the heights and depths of all of the sub-expressions in a
formula are now calculated. These are currently used to:
- Correctly position superscripts, subscripts, numerators, and denominators
- Adjust the height and depth of the overall expression so it takes up the
appropriate space
- Because we have to add attributes (height and depth) to every attribute, I
have changed the way DOM nodes are assembled. Now, instead of assembling the
DOM elements inline (which is a problem because we need to track
height/depth, and we shouldn't (and can't in IE 8) attach raw attributes to DOM
nodes), we assemble a pseudo-DOM structure with the extra information, and
then actually assemble it at the very end.
The main page also now has an updated expression to show off and test the new
and improved parsing.
Test Plan:
View the main page, make sure that the expression renders. Make sure
that the tests pass. Make sure that expressions have the correct calculated
height (this is most easily tested by viewing them on the main page and making
sure that the top of the expression lines up with the bottom of the input box).

Summary: Make the makefile copy files into the correct places in all
three repos. (note, the khan-exercises location might change since we
don't want to have two copies of things, but it's where it is in my
setup right now)

Summary:
Make our own parser that doesn't use jison, so that we can handle
funny TeX syntax, and to make it smaller.
Test Plan: Make sure the tests pass with the new parser.

Summary: Rename all instances of mjlite -> katex
Test Plan: Run the local server, make sure things still work.

Summary:
Get the styles into a form that they can be directly copied over to
khan-exercises, with no changes. Mostly just changing #math to .mathmathmath
and adding a font style and size.
Test Plan: Make sure that the local test still works.
