JavaPermutationTools (JPT): A Java API for computation on permutations and sequences

The JavaPermutationTools (JPT) API provides Java classes that enable representing and generating permutations and sequences, as well as performing computation on permutations and sequences. It includes implementations of a variety of permutation distance metrics as well as distance metrics on sequences (i.e., Strings, arrays, and other ordered data types).

New in this release: Added functionality to the Permutation class, and added normalization for permutation distance measures.
