Summary:
Add support for all of the other operators, including the ones with symbols and
limits. This also fixes the bug where subscripts were shifted the same amount as
subscripts.
To accomplish this, the domTree.textNode has been repurposed into symbolNode
which is no longer an actual text node, but instead represents an element with a
single symbol in it. This lets us access properties like the italic correction
of a symbol in a reasonable manner without having to recursively look through
children of spans.
Depends on D13082
Fixes#8
Test Plan:
- Make sure tests work
- Make sure huxley screenshots didn't change much, and new screenshot looks good

Summary:
Add a way to automatically build vlists correctly. Previously, we built
vlists manually in ~4 different places, which made it difficult to manage
changes, and led to a large amount of duplication in the less. This also fixes
the vlist construction in safari, where the `display: inline-table` wasn't being
applied because of CSS specificity. This leads to the only significant change in
the huxley tests, with the vertical spacing.
Test Plan:
- Make sure the tests still work
- Make sure most of the huxley screenshots didn't change, and that the new
changes are insignificant.
- Make sure vlists now work in Safari
- Make sure the change to the VerticalSpacing screenshot is caused by the
fix-baseline span now correctly applying `display: inline-table` by creating
the construct in master and adding `display: inline-table !important` to the
`.fix-ie` css rule

Summary:
Follow the TeXbook instructions on how to construct square roots. Using
makeCustomSizedDelim, this becomes nearly trivial.
Test Plan:
- Make sure normal tests work
- Make sure the new huxley test looks good, and other huxley tests haven't changed.

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

\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\|

- Look at huxley screenshots (not here yet :( ) and make sure they look good
