> Got this cool idea from one of my customers: allow people to write one-liner counter increment functions on top of Scrunch, ala:
> val pc: PCollection[S] = ...
> pc.map(...)
>     .increment("CounterGroup", "CounterValue")
>     .incrementIf(x => x.foo == "bar")("CounterGroup", "CheckBar")
> etc.
