a couple of updates

Practiced the final presentation yesterday- I've made a few changes to the slides and documentation for tomorrow. They'll be available in the new 'Documentation Repository' link in the Related Links section soon.

Other than that, I'm in the middle of debugging some older stuff and some newer stuff.

1. fixed termReader() so that it reads the last term in the XML file
2. improved the efficiency of xmlEsc()
3. IN PROGRESS- working on some problems in the ranking comparison functions.
