Please note: this is a corrected/updated version of the previous documents on this page. Note the version number and date below.

This version (1.74) was LaTeX'd on 2001/09/12.

If for some perverse reason you want to see the thesis form of this (which takes up a lot more paper and is slightly more wordy), email me at:
