Bradford N. Cross updated MATH-169:

    Attachment: RankPatch.txt

Fixes issues with last patch:

-does not include any refactorings, only new features

-removing the rolling package, adding rolling rank, summary and moment stats into respective

notes for future change:

-rolling percentile uses a data structure called SortedDeque, i am exploring solving the selection
