minor checks and enabling threshold computations
Merge pull request #678 from karlnapf/master

more work towards threshold computations
Added custom evaluations support for model selection output
Fixes for MALSAR JFL
Added missed initialization of custom evaluations array
Added subset support for multitask algorithms
Gracefully fallback to loop based matrix multiply
Changed lapack guard in sgmatrix
FITC computations are now accurate!
Cleaned up some of the code
Updated MKL linking flags
Removed wrong enum keywords in lapack wrappers
Removed one more wrong enum in lapack
Multitask crossvalidation support
kernel matrices are now pre-computed: Features have to be stored in
memory anyway, and this is much faster
re-added assertion that should never fail
doc updates
made p-value computation with gamma more modular
added compute_threshold
