Reviewed r14228 and r14229. Changes look good wrt the actual source.

However, the possibility to set the seed for one instance provider is never used or have I overlooked the according call?

I still can't reproduce the datasets, because I don't know the seed which has been used to create the problem data => I don't see an improvement in r14228 or r14229 as long as the seeding methods are not used anywhere in HL or the seed is accessible from the problemData or dataset.
