Subject [jira] [Created] (CRUNCH-323) Add a section on getDetachedValue to the user guide

Gabriel Reid created CRUNCH-323:
-----------------------------------

             Summary: Add a section on getDetachedValue to the user guide
                 Key: CRUNCH-323
                 URL: https://issues.apache.org/jira/browse/CRUNCH-323
             Project: Crunch
          Issue Type: Improvement
          Components: Site
            Reporter: Gabriel Reid
            Assignee: Gabriel Reid
            Priority: Minor
         Attachments: getDetachedValue.patch

The use of the PType#getDetachedValue is a useful bit of information, and a common gotcha
when working with Crunch and MapReduce. A section explaining how to deal with retaining references
within a DoFn should be added to the user guide.
