55.Commit:	fixed MICRO vs MEASUREMENT conflict
mskoenz

DONE:
- msk_v1_sim now runs again in all files
- problem that MICRO_BENCH and MEASURE used the same clock resolved (MICRO has own clock2 clock)
- cleaned namespaces in mkl and custom rng
- tested custom_engine vs mkl_engine -> mkl only 1.3x faster on my machine (see rng_performance_example)
- checked algorithm, mkl doesn't return same numbers as the other mt19937 engines since it is sfmt19937
TODO:
- python framework for nice plots (plot data from MICRO_BENCH)
- show optimization history (baseline -> v1 -> v2 ....)
