Contributed stages from Mark Southern
-------------------------------------

                 Key: SANDBOX-325
                 URL: https://issues.apache.org/jira/browse/SANDBOX-325
             Project: Commons Sandbox
          Issue Type: New Feature
          Components: Pipeline
            Reporter: Ken Tanaka


Some stages were submitted. I'm not sure where they should go. Maybe SessionStage and CommitStage
could go under

    package org.apache.commons.pipeline.stage.contrib.hibernate;

and GroupStage and UngroupStage could go into

    package org.apache.commons.pipeline.stage.contrib;

I've looked over the code but haven't run these yet. These are here so people can work with
them and comment on improvements and how to add them to the pipeline codebase.

I might contribute back a few Stages that I've written? The first two have dependencies on
commons-collections and the last two on Hibernate. Maybe they could go into a user-contrib
project?

object.

session.
> CommitStage:   Calls Session.save on each Hibernate object and commits with a predefined
frequency.
