This is my first approach to an openmp version of the code. Still has to be crosschecked against purely serial version. #1

Most of the loops over all the grid points have been parallelised with openmp. There is a new command line variable for adjusting the number of threads openmp uses: "--omp_nthreads " . Furthermore OMP has to be defined to enable openmp instructions either via the -DOMP compiler option or a config.h (which doesnt exist so far).
Some statements only necessary for verbose output in the loops are compiled conditionally ( #ifdef DEBUG). I have included a cmake make-file into the commit that I use for development.
