Initial bug-fix and documenting

Made things work, BUT it's still throwing way too many false positives.
Timing and line-count results are in test-results.txt but raw result
files are not. numb-hunt is returning far more false positives than
find_ssns for this set of my home folder on a Mac. However, it's still
faster! More work will be done soon to quantify the differences and
find how to remove false positives.
