renamed matmul to 1-core matmul
micro: helptext fix
micro: renamed binary according to git mv
fix: change coordinate handling to how it supposed to be

* allocate only one core instead of all
* use coord 0, 0 from then on
fix: Makefile didn't use E_CXX at all
beauty: now that c++1y works we can use proper enums
single core matmul works now
use O3 to get the correct number of floating point operations
fix: fmadd is counted as one op

therefore, double fpops
reorder loops to shave of 1/10 of the needed cycles
