chartl 328f89f66a Minor changes to MannWhitneyU:
- Comment fixes to better explain why two-sided test wants to use the LOWER (not higher) value for U
 - Much more direct testing of MWU functions
 - Uniform approximation was always using the < cumulant (sometimes the > cumulant should be used instead)
 - Uniform approximation currently not used (regime in which it was being used was not the right one -- not necessarily bad, but not an improvement over normal)
    + this particular approximation is for major imbalances of the form m >> n. Code may be altered in the future to use this method for this particular regime, if the method's not too slow.
 - Hook into one-sided test.

RegionalAssociationRecalibrator: NaNs were being caused by presence of Infinity and -Infinity values out of the walker. Currently I'm just re-setting them to arbitrary post-whitened values, but the walker will be changed to prevent output of these values, and the "fix" will undone.

chartl 5a79f16ea4 Fixed an edge case where an exception was thrown if either of the sets was empty for the MWU test. Also altered the output format so U itself is not printed (which though interesting, isn't so useful for recalibration), but rather a value I call V (really the deviation of U from its expectation).

chartl 60ddc08cdf Added a boatload of new case-control association modules. Switched the U-test to use longs rather than ints (it just so happened that I overflowed and started getting negative U statistics. Not good.) Added the ALL association type for ease of specifying that we want to throw the book at something. Added an svn-commit.tmp~ because i can't get rid of it even with --force. Hopefully I can remove it after.

chartl a40a8006b5 Added in unit tests for the statistics calculated by the test runner; and bug-fixes to the calculations; so we have some assurance that the statistics coming out the back-end are correct.
