Add a Dockerfile for huxley tests

Browse Source 
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

### How to generate huxley images
---------------------------------
Now you too can generate huxley images from your own computer, and (hopefully)
have them look mostly the same as the current ones! To start, make a docker
image from the included Dockerfile using a command like
sudo docker build --tag=huxley .
from within this directory (note you need to have docker installed and running
for this to work). This will build a docker image with the huxley tag,
which you can then use to run dockers based on them.
This huxleyfile is set up such that it will run everything and generate all the
huxley images when the image is run, so no interactive input is required. All
that you need to do is mount the KaTeX directory you want to test into the
`/KaTeX` directory in the docker, and run the huxley docker, like so:
sudo docker run --volume=/your/KaTeX/:/KaTeX huxley
The `--volume=/your/KaTeX:/KaTeX` switch mounts your KaTeX directory into the
docker. Note this is a read-write mounting, so the new huxley images will be
directly placed into your KaTeX directory.
Since this docker is very self-contained, there should be no need to do
interactive management of the docker, but if you feel the need, you can read the
General Docker Help section of the MathJaxFonts docker readme.
That's it!

### How to generate MathJax fonts
-----------------------------
---------------------------------
It's really simple (now)! Just make a docker image from the included Dockerfile
using a command like
sudo docker build --tag=mathjaxfonts .
sudo docker build --tag=mathjaxfonts .
from within this directory (note you need to have docker installed and running
for this to work). This will build a docker image with the mathjaxfonts tag,
which you can then use to run dockers based on them. Then, run a mathjaxfonts
docker with
sudo docker run --interactive --tty --name mjf mathjaxfonts /bin/bash
sudo docker run --interactive --tty --name mjf mathjaxfonts /bin/bash
We name this docker "mjf" so we can reference it later when we want to copy the
files off. (If you get an error about the name being in use, perhaps because you
are trying to create another docker, you can either delete the old docker with
sudo docker rm mjf
sudo docker rm mjf
or use a different name.) This will get you into the docker in the root
directory. From there, cd into the `/MathJax-dev/fonts/OTF/TeX` directory, and
run
make ttf eot woff
make ttf eot woff
to build all of the fonts that we need. Finally, leave the docker and copy all
the files off with
docker cp mjf:/MathJax-dev/fonts/OTF/TeX/ttf ./
docker cp mjf:/MathJax-dev/fonts/OTF/TeX/eot ./
docker cp mjf:/MathJax-dev/fonts/OTF/TeX/woff ./
docker cp mjf:/MathJax-dev/fonts/OTF/TeX/ttf ./
docker cp mjf:/MathJax-dev/fonts/OTF/TeX/eot ./
docker cp mjf:/MathJax-dev/fonts/OTF/TeX/woff ./
(note we're using `mjf:` to specify the name of the docker we created above)
Compile the fonts into a single directory
mv {ttf,eot,woff}/* ./
mv {ttf,eot,woff}/* ./
Remove the WinIE6 and WinChrome fonts
rm KaTeX_Win*
rm KaTeX_Win*
And you're good to go! Don't forget to update the font metrics with the
metric_parse.rb script once you're done.

When you quit the docker, it will stop the docker from running. If you want to
reattach to the docker, you can start it again with
sudo docker start mjf
sudo docker start mjf
and then attach with
sudo docker attach mjf
sudo docker attach mjf
Alternatively, if you want to detach from the docker when you're done instead of
quitting and stopping it, you can detach with `C-p C-q`, and then re-attach with
sudo docker attach mjf
sudo docker attach mjf
To see a list of your current dockers, you can run
