Aadhavan Srinivasan b55b80ec6c Updated TODO
I didn't like the existing capturing group implementation, so I moved
that to a separate branch. This branch does not (at the moment) any code
relating to capturing groups.

Aadhavan Srinivasan 137ea3c746 Made findAllMatchesHelper non-recursive, added pruneIndices (improved performance) and more changes
I made findAllMatchesHelper a non-recursive function. It now only
returns the first match it finds in the string (so I should probably
rename it).

These indices are collected by findAllMatches and pruned (to
remove overlaps). The overlap function has also been rewritten, to make
it (I believe) less than O(n^2). I also used the uniq_arr type to make
checking for uniqueness O(1) instaed of O(n) (as it was with
unique_append()). This has resulted in massive performance gains.

There's been a lot of changes here, and I probably haven't documented
all of them.
