struct wielding::generate_aggregator< _vsize, ic_type, functor_type, typename >

generate_aggregator is very similar to indexed_aggregator, but instead of managing and passing a coordinate to the functor, the functor now manages the argument side of the operation: it acts as a generator. To make this possible, the generator has to hold run-time modifiable state and can't be const like the functors used in the other aggregators, where the functors are 'pure' in a functional programming sense. A 'generator' functor to be used with this body of code is expected to behave in a certain fashion:

• all of it's state which stays constant and shared by all invocations has to be present after construction.
• the generator is trivially copyable
• copying the generator produces copies hoding the same shared state
• the generator has a 'reset' routine taking a coordinate. This routine initializes state pertaining to a single 1D subarray of data to be processed in a worker thread.
