finished algorithm 31
Did some renaming and fixed while loop to just increment the index
Changed package name and some variable names
disposed of variables
Made more changes and think we are finished.
rewrote algorithm after getting some help
changed package to operators
Made lots of changes and tested individual methods
Merge remote-tracking branch 'long0385/Algorithm31' into sus
Finally got Stochastic Universal Sampling merged in, fixed, and (I
think) tested and working.
