Summary:
Added stacked delimiter support for more delimiters. Split out delimiter
functions into its own file, and split out some tree building functions into a
common file. Supports the empty `.` delimiter with \left and \right, and doesn't
try to produce huge /, \backslash, <, or > delimiters. Depends on D7844
Test input:
\left( \left) \left[ \left\lbrack \left] \left\rbrack \left\{ \left\lbrace
\left\} \left\rbrace \left\lfloor \left\rfloor \left\lceil \left\rceil
\left\langle \left\rangle \left/ \left\backslash \left| \left\vert \left\|
\left\Vert \left\uparrow \left\Uparrow \left\downarrow \left\Downarrow
\left\updownarrow \left\Updownarrow {x^{x^{x^{x^{x^{x^{x^{x^{x^{x^x}}}}}}}}}}
\right.\right.\right.\right.\right.\right.\right.\right.\right.\right.
\right.\right.\right.\right.\right.\right.\right.\right.\right.\right.
\right.\right.\right.\right.\right.\right.\right.\right.
Test Plan:
- Run the test input, see that it works
- Run the tests, see that they work
- Look at huxley screenshots (not here yet :( ) and make sure they look good

Summary:
Instead of using the metrics from our generated TTF files, use the fonts that
TeX ships with. Pull the mapping out of the MathJax-dev repo from makeFF to get
the correct mapping of metrics to font characters, and use our own tfm reader to
extract metrics out of the tfm files into a useable format. Add a README and
Makefile rule to make this process easier in the future.
Also remove the silly 0.05em we put on supsubs because our italic correction
works now.
Test Plan:
- Run huxley tests, see that changes are because of font metric changes.
- See that the extension piece of `\bigl |` now extends above the top, as it is
supposed to.
