This won't earn style points in Python, but here we establish a couple
of helpful mappings variables. The reason this is helpful is that the
end result is simply an ordered set, the CSV file. But we still may
want to manipulate the values arbitrarily before writing that file.

Also note that the current Auto Wx InfoEx documentation shows these
keys in a graphical table with the "index" beginning at 1, but here we
sanely index beginning at 0.
