Changed Wilcoxon so that it returns the lower U.
Merge branch 'release-1.2' into develop
Made mincTtest and mincPairedTtest Compatible with mincFDR
To do so, the degrees of freedom and stat-type needed to be added as attributes.
Additionally, the result needed to be converted to a matrix
Modified mincWilcoxon so it can handle ties.
Merge branch 'release-1.2' into develop
Added Tests for mincFDR and mincTtest,mincPairedTtest and mincWilcoxon
Fixed mincFDR to work with mincWilcoxon Tests
Added new functions to NAMESPACE
Added sfInit and sfStop
Added test to check if snowfall exists
Delete test bed data after execution of tests
Fixed syntax error in test_mincSummary
Fixed mincFDR to accept NAs

Merge branch 'develop' of https://github.com/mcvaneede/RMINC into develop
* working version of mincLmer, but with lots of details left to take care of
* added log likelihood for lmer
* added chisq to mincFDR
* made lmer code slightly more generic
* added small test-bed
* added error handling to mincLmerExtractVariables
* added function to estimate of degrees of freedom to mincLmer
* added ability to run mincFDR on mincLmer output (with lots of warnings)
* added function to convert vector coordinates to minc voxel coordinates
* added function to grab a number of random voxels
* added sge as an option for how to run mincLmer
* some more documentation
* optimization of mincLmer and mincLmerOptimize - runs 50% faster now!
* a few more test functions in test_mincLmer
* added parametric bootstrap (though with limited options and still missing documentation)
