             Summary: Provide a "Scratchpad" request-scoped service, as a way 
of passing arbitrary user data from one place to another.  One use case is to 
coordinate the response of bulk actions.
                 Key: ISIS-653
                 URL: https://issues.apache.org/jira/browse/ISIS-653
             Project: Isis
          Issue Type: New Feature
          Components: Core
    Affects Versions: core-1.3.0
            Reporter: Dan Haywood
            Assignee: Dan Haywood
             Fix For: core-1.4.0


This builds on ISIS-652 (request scoped).  The Scratchpad service itself is 
basically a wrapper around Map, with signature:

get(Object key)
put(Object key, Object value)
clear(Object key)
