#3 Group hits together to identify a collection

Some ideas as to how this grouping would work (as of [e79ee82a72]): - Each hit would need to check to see if there are any hits around it, if so start collecting them (recursive, at least until we hit a hit that has already been added to the collection) - Try to average the points (this might allow me to get the center of the collection, which will be used as the main point for determining direction) - Track total number of hits within the collection (this will allow me to determine if the collection is the same one, for when we iterate over the frames to determine direction)
