Implemented basic openmp in the inner region-likelihood-evaluation. Remains to be seen whether this has any significant effect.

Performance program now runs and supports three test modes.
It is now possible to use either the openmp version or the non-parallelized version of get_region_like. Useful for testing. Will do the same with other functions later if needed.
Rearranged the CRITICAL OMP directive to be outside the loop - now almost linear speedup with six processors.
Fixed bugs in region_mod and added timing for each step in spectral_regions
