Title: Small improvements + Histogram

A few small improvements:
- set the cascading.app.name property to the job name
- an overridable listeners method in Job for adding cascading FlowListeners
- separate out createLocalTap so it can be easily overriden; useful for the LocalTap wrapper (coming to Maple soon)
- an each() method on RichPipe for easily integrating with cascading Function implementations
- a Histogram class for efficiently computing binned CDF, percentiles, etc
