hella bugs.  Left off on the nextStep method in usersRankList need to add ":" to the threeQuery strings.  In general I just realized my binaryInsert only actually inserts when a grader picks equal so I need to correct that and deal with the cases when b is odd which actually shouldn't be too bad.  Just update __Insert to the desired outcome.  The base case seems ez lets hope the general one is as well.
