Summary:
Add the dockerfile that I've been using to make huxley screenshots so
others can test their changes by making huxley screenshots. Include a readme
about how to use it correctly.
Test Plan: - Use the dockerfile by running the given commands, see it works

Summary:
Add support for math-mode accents. This involves a couple changes.
First, in order to correctly position the accents, we must know the kern between
every character and the "skewchar" in that font. To do this, we improve our tfm
parser to run the mini-kern-language and calculate kerns. We then export these
into fontMetrics.js.
Then, we add normal support for accents. In particular, we do some special
handling for supsubs around accents. This involves building the supsub
separately without the accent, and then replacing its base with the built
accent.
Finally, the character in the fonts for the \vec command is a combining unicode
character, so it is shifted to the left, but none of the other characters do
this. We add some special handling for \vec to account for this.
Fixes#7
Test Plan:
- Make sure tests pass
- Make sure no huxley screenshots changed, and the new one looks good

Test Plan: Ran unit tests. Looked at `\blue{\displaystyle \left(\dfrac{a^\sigma}{\sin \theta}\right\Updownarrow \intop_{1/2}^{z^z} \sum_{i=0}^\infty x \,dx}` in Chrome and saw the future in my eyes.
