New Revision: 584700

URL: http://svn.apache.org/viewvc?rev=584700&view=rev
Log:
Added 'description' field and accessor methods to the ModelField and ModelViewEntity.ModelAlias classes to store the field level description specified in the entity definition (<description></description> tags).
Added new optional attributes to the alias-all element: function and group-by. If specified then to all the aliased fields the function and/or group-by element will be applied.
In ModelViewEntity, added new method to get the list of group-by fields as a subset of the passed in list: this is useful to get the list of group-by fields limited to the felds that are in the select clause.
