las3_pub / predictable_parallel_patterns

Now all algorithms are used without the parallel pre-/suffix and the for_each method has an specialization for integer ranges.

Please note that this does currently not execute, but only removed the 'old aspecs'. We are still missing launching the root fork_join task.

This resulted from an merge gone wrong.

There are serval ways we could optimize the calls, but for now this should be enough for first tests.
