Log:
Intermediate commit in the ProbABEL pvals branch. This commit comprises the work done in the first week of January. The binaries build, but checks still fail.
CAUTION: Work in progress!
This commit contains:
- debug code/comments that need to be removed!
- merge from trunk until r1911
- implementation of the quadratic form of the Wald statistic (finally). Still need to add a command line option to enable it. Also need to carefully check in which cases the Wald can be used and when to fors use of LRT.
- more Doxygen documentation
