Emily Eisenberg	7e5e6a90d3	Add the \KaTeX command ... Summary: Add a command to print out a TeX-style logo for KaTeX. I think the code is okay, but suggestions for the design of the logo are most welcome (I'll post screenshots soon). Test Plan: Make sure \KaTeX renders, and the tests still succeed.

Emily Eisenberg	383ca01434	Sync with Khan-exercises ... Summary: Add some things in to make this more useful to khan-exercises.

Ben Alpert	c08fadfaa9	Parse single superscripts and subscripts ... Summary: Add the ability to parse lone `^x` and `_y`, etc. This basically just involves more checking of cases in the increasingly ugly `parseAtom` function. Also, now we manually check for the cases of double superscripts and subscripts. Test Plan: Make sure the tests pass. Make sure things like `^x` and `_y` parse.

Ben Alpert	e29fe0c683	Grosser color support for prettier results ... Test Plan: `\orange{x}\blue{-4}`, `\orange{x-}\blue{-4}` look the same after desaturation as `x-4` and `x--4`. In addition, `\orange{x}\blue{{-4}}` looks appropriately atrocious (i.e., has no space whatsoever).
