* 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)
* Merge branch 'mincLmer' into develop

* fixed some resulting merge bugs in mincFDR.mincMultiDim
* created Rd files through roxygen2
* some documentation updates
