This tests against Node 0.10 (latest stable) and 0.11 (latest dev).
Test Plan: Crossed fingers. In theory we'll see this at https://travis-ci.org/Khan/KaTeX as soon as I push it.

Summary:
The `\dots` and `\dots{c,o,b,i,m}` commands do more than just show characters,
they add extra space and `\dots` also looks ahead to determine what kind of
environment it is in (see [this math.sx post]
(http://tex.stackexchange.com/questions/122491/difference-of-the-dots)). We
can't support that yet, so remove them.
Also, add comments to the extract_ttf script to show what caracters we are
extracting metrics for.
Test Plan: - Make sure tests work

Fix getting a NaN maxFontSize in makeVList because symbolNodes don't have a
maxFontSize property.
Test plan:
- Make sure no huxley screenshots changed
Auditors: alpert
Summary:
Upon switching over from ttf metrics to TeX metrics, we lost metrics for a
couple of the characters that are dynamically generated by TeX. Thus TeX doesn't
have metrics for them, but our fonts do have the characters because the MathJax
scripts also dynamically build them. This adds the ability to extract metrics
from the generated font files so that we can use the generated characters
correctly. A better solution would be to dynamically generate the characters
ourselves, but that is much harder, and will be left to a future time.
Test Plan:
- Make sure typing "\neq \cong \text{ }" produces no warnings in the console.
- Make sure huxley screenshots look the same

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

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

some buildTree tests. Add some checks make utils.js work in node. Add support
for jasmine-node, to allow for command line unit testing.

Fix the \frac and \overline lines so they actually render at the correct sizes
(i.e. don't get smaller when in script and scriptscript sizes). This also seems
to fix#33.
Test Plan:
- Make sure new huxley screenshot look good.
- Render
\frac{1}{\Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{\frac25 \pi}} =
1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} {1+\frac{e^{-6\pi}}
{1+\frac{e^{-8\pi}} {1+...} } } }
at small font sizes like 30pt and smaller, see that it looks much better

Summary:
Rewrote the parser to make this work, and added a bunch of tests to make sure
this does work. In the process, refactored all of our functions into a separate
file, functions.js. Added a bunch of comments to Parser.js. Also, update jasmine
so we can make our tests better, and add a lint_blacklist.txt to not lint bad
jasmine stuff.

Summary:
This incorporates the changes to add a KA copyright, and to generate the woffs
from the ttfs, not the otfs.
Test Plan:
- Run huxley tests, see very little has changed (it looks like all the images
shifted back down ~1/2 pixel, the opposite of what happened in ad97dab19c
when we started making our own woffs, which means we probably are now
generating woffs the same way fontsquirrel does)
