We need to support creation of REST web service using patterns other than from
JPA entity classes.  The wizard would have:
- First page allowing selection of different patterns.  Initially, 2 patterns
are supported: container-items and client-control.  Container-items is default
selection.
- Second pages for all patterns should allow user input name of the resource and
have default values derived for all other parameters:  class names and URI's.
- Selection and typing in of MimeType should be allowed for both of these
patterns.  text/xml is the default selection.
- Representation class selection should allowed for XML mime type (and later for
Jason).
