[WIP] [FEEDBACK] proposed API for "concurrent analytics"
See https://issues.apache.org/jira/browse/QUARKS-156
Looking for comments for the API (not the impl yet).
This proposed high level concurrentMap() is to "make the simple simple". I
suspect some lower level assets, that could also be directly used by apps, may
be created to realize its implementation (more on that to come).
Questions:
- happy with the semantics and signature?
- name OK?
- should it be ``TStream.concurrentMap()`` instead?

> Consider a pipeline of *independent* analytics, each enriching some tuple
> with additional information:
> ```
> readings<T> -> A1 -> A2 -> A3 -> results<R>
> ```
> If the analytics are independent and non-trivial / time consuming, there's a
> desire to run the analytics concurrently for each tuple with a graph
> logically like:
> ```
> /-> A1 ->\
> readings<T> -> |-> A2 ->| -> result<R>
> \-> A3 ->/
> ```
> I'm using the term "concurrent" instead of "parallel". Java8 Streams', and
> IBM Streams Java API's and SPL's, use of "parallel" is for "parallel-tuple
> processing": multiple tuples, each being processed in parallel in its own
> "channel" of the same replicated pipeline of operations.
> I'm going to use a pull-request to capture API proposals/discussion.
