Added the indexOf(T[]) and longIndexOf(T[]) methods, without implementations.
This test case now has a working algorithm to directly solve indices given a permutation.
Added a test case that demonstrates how to compute a permutations size from the
size of a related permutation.
Updated the combinations code.  It is now properly computing indices.
Add a test for combinations.
Updated the permutations code, it contained a strange winding in the results.
Added a new permutations class with an easily predicted ordering.
Removed the DisplayPermTest.
Updated the abstract permuations test, so that it does not consider order, just results.
Reverted changed to the permutations ordering.  It was causing improper results to be generated.

This reverts commit f3c8a35a4fe52b34b7e65c90814fa2ef06dcffc2.
Corrected the longIndexOf function for Permutations.
Improved the abstract combinatorics class.
Added a new engine for permutations, based on Permutations2.
Removed dead code in math utils.
Improved object recycling in math utils.
Improved speed of indexOf in Combinations.
Improved speed of indexOf in Permutations.
Improved comments for works in progress.
Removed dead code.
Throw UnsupportedOperationException for methods that have not been implemented.
Renamed Permutations2 to something meaningful.
Added missing license files.
