v1.3.0: Additional test statistics and accumulated updates

• Add arbitrary test statistics to new find_sets.py script, including predefined exclusivity, any co-occurrence, and all co-occurrence statistics -- see the WExT wiki for details.
• Add more accessible random seed to compute_mutation_probabilities.py script for mutation matrix permutations.
• Add optional FDR threshold to new find_sets.py script to limit output to statistically significant sets.
• Add additional examples, including those for new test statistics.
• Update documentation.

v1.2.0: Accumulated updates since ECCB/Bioinformatics 2016 release

This version of WExT includes accumulated updates after the last release, including

• bug fixes,
• a more accurate mutation probability/weight matrix,
• new examples, and
• documentation updates.

1.1.0: Experiments for camera-ready ECCB/Bioinformatics 2016

• Use Fortran to generate permuted matrices
• Rename tests: "weighted" -> "WRE", "unweighted" -> "RE", "permutational" -> "RCE"
• Update experiments to use renaming and to match new table/figure numbers
• Other, minor changes

1.0.0: ECCB 2016 submission

Initial release of the weighted exclusivity test code, including a script of commands for reproducing the experiments from the ECCB 2016 submission.
