> Pipeline stage to filter out objects based on some criteria. This can be done
> today by writing a stage class with a conditional emit call. As with functors
> and other predicate classes this new stage aims to simplify the coding of
> simple filters. I will be attaching the classes and tests after I submit
> this. The only filter included is generic and provided as an example. We have
> been using this filter mechanism with custom filter classes to make fairly
> complex object flows via configuration alone allowing for great flexibility
> and no need to build any new code or jars.
