Found an edge case with the glob call that would cause it to loop inside
the same directory.
Was able to rethink the blob statement and everything seems more sane
for now.
Added additional test to the edge cases.
Changed alpha/beta vercomp conditions to subtract more to avoid issues
with low number comparisons.
