Throttled Parallel ForEach

The ThrottleParallelForEach activity is similar to the ParallelForEach<T> activity with the one exception that it allows setting a concurrency factor to restrict the number of simultaneous branches to execute. The ThrottleParallelForEach activity derives from NativeActivity, because it needs to schedule other activities (the child activities) and this is only accessible through the NativeActivityContext class.
