Description

Name: rmT116609			Date: 11/30/2001



I request having a field  EMPTY_SORTED_SET in Collections, just like EMPTY_LIST,
EMPTY_MAP and EMPTY_SET. I right now have a function with a parameter type 
SortedSet, and I want to provide it with an empty set.

EVALUATION Will investigate adding Collections.emptySortedSet method. Adding the field is not necessary.
