This file will be the basis of a new unit test.

test_convert_tabletabular_to_deluxetable will copy it (making a new file), operate on that new file, assert that it equals some specific thing we have in mind, and then delete the intermediary file.
Added the 'comparison' file for	the aforementioned test.
Wrote convert_tabletabular_to_deluxetable. It passes tests, looks good.
Wrote a test for the deluxetable converter. Passes.

It does some file magickery.
Finally figured out how to get a table to write pretty.
Renaming some columns for easier LaTeX table fitting.
Wrote `write_and_correct_latex_table()`, which seems to work well!

It's based on the code that I'd written in table_latex_strings_test under the 'if write:' keyword, but I abstracted it out.

Future upgrades: much more control over the latexdict parameters. Especially with \rotate, which is probably not desired very often or ever.
Replaced the write: section in table_latex_strings_test completely.

Now it calls the code that I moved up into the write_and_correct_latex_table function (which used to live here).
Code style cleanup (some lines were over 80 chars).
This version writes a table that LaTeX SUCCESSFULLY RENDERS. hellyes.

Unfortunately the table is also TOO WIDE TO FIT ON THE PAGE EVEN WHEN ROTATED, so I'll deal with that by cutting precision and compressing column names.
Changes meant to *squish* the table columns thinner.

Also improves conciseness I suppose.
