<commit_before>-- update the JUnit library and make any needed changes

-- consider implementing a 3D voronoi

-- implement perfect hashing one day. not currently needed.
   openjdk has an implementation of
   "A Practical Minimal Perfect Hashing Method" - <NAME>,
   <NAME>, and <NAME>, 2005 
   in PerfectHashBuilder.java 

-- consider refactoring the code for permutations (Shuffle), combinations
   and partitions to place in one package/directory.

-- for improving the current NearestNeighbor2DLong
   could consider locality based hashing along y axis.

-- when begin to include more than 2 dimensions in clustering project,<commit_msg>adding a note to the todo list<commit_after>-- update the JUnit library and make any needed changes
