Added the GUI buttons for the new way of handling test documents
The new way of handling test documents is in. There are still some
things to be worked out (including an unknown folder by default,
statistics calculation)
Everything should be working as it used to, but with the new
infrastructure (except for having an _Unknown_ folder by default) will
do that next.
Fixed a bug where you couldn't add documents to the _Unknown_ folder via
the add test docs button
Improved messages when attempting to add documents more than once.
Documents will now automatically be filtered out if they have already
been added to test or training sets, and will notify the user of which
author has that document.
Updated the Docs tab instructions
Switching over to using new format to statistics part 1...
Fixed a bug where sometimes it wouldn't properly detect that a document
had already been added.
For train/test statistics, the document title is used to match to the
correct test document, and that document's author is used for statistics
calculation. If the author is "_Unknown_" the document will be exempt
from statistics calculation
Made it so that if you're skipping a long list of documents the pop up
will not list them all (all skipped documents will still be recorded in
the command line)
Accidentally removed some lines in the writeToXML method at some point.
They're back and that should be working again. XML files using the new
format can be created and loaded properly. Old format XMLs will have all
documents loaded into the _Unknown_ folder
