Updated text and code

Here are some things I changed:

1. The preamble (to use XeTeX instead of latex, so that unicode characters and modern fonts can be utilized). To compile this file using XeTeX, enter the command "xelatex TechManual.tex". Otherwise everything is the same.

2. I commented out the DMX graphics (with a % at the beginning of the line which specifies the filename) because the graphic was not in your repo. Also I incrementally numbered the DMX captions, as captions must be unique (they can act as labels).

3. I added comments in a few places. Usually these were questions about what you mean in a given passage. The comments are in {comment} environments. Just remove them when you are done.

4. The Contents page (make sure to compile twice to get the contents right) is a good place to review the whole document for consistency. If you add, remove, or change the headings for any of the sections, check the Contents to make sure everything is consistent (the indenting is your best clue).

5. I also removed the "Ignore this part" bit. I think it's clear that you are being humorous and lighthearted about how to read the manual.

6. I have added my fork to your laptop in the directory ~/Documents/rosslaird/Tech-Manual. It compiles without errors on your machine.
