----------------------------------------
This looks good. I'll commit to trunk if tests pass.

> We find ourselves wrapping {{StoreFuncs}} often and have written a
> {{StoreFuncDecorator}} and a {{StoreMetadataDecorator}} class. These make it
> easy to subclass and decorate only select {{StoreFuncs}} methods.
> This is conceptually similar to the wrapper helpers in the Java servlet API:
> http://docs.oracle.com/javaee/5/api/javax/servlet/ServletRequestWrapper.html
> http://docs.oracle.com/javaee/5/api/javax/servlet/ServletResponseWrapper.html
> I think these would make useful additions to Pig.
