"Overrides" the ImmutableMultiset static methods that lack ImmutableSortedMultiset equivalents with deprecated, exception-throwing versions. This prevents accidents like the following:
   List<Object> objects = ...;
   // Sort them:
   Set<Object> sorted = ImmutableSortedMultiset.copyOf(objects);
   // BAD CODE! The returned multiset is actually an unsorted ImmutableMultiset!

While we could put the overrides in ImmutableSortedMultiset itself, it seems clearer to separate these "do not call" methods from those intended for normal use.

Not supported. Use ImmutableSortedMultiset.naturalOrder(), which offers better type-safety, instead. This method exists only to hide ImmutableMultiset.builder() from consumers of ImmutableSortedMultiset.

   * We would like to include an unsupported "<E> copyOf(Iterable<E>)" here, providing only the

   * likewise for the Iterator equivalent). However, due to a change in Sun's interpretation of the
   * JLS (as described at http://bugs.sun.com/view_bug.do?bug_id=6182950), the OpenJDK 7 compiler
   * available as of this writing rejects our attempts. To maintain compatibility with that version
   * and with any other compilers that interpret the JLS similarly, there is no definition of
   * copyOf() here, and the definition in ImmutableSortedMultiset matches that in
   * ImmutableMultiset.
   *
   * The result is that ImmutableSortedMultiset.copyOf() may be called on non-Comparable elements.
   * We have not discovered a better solution. In retrospect, the static factory methods should
   * have gone in a separate class so that ImmutableSortedMultiset wouldn't "inherit"
   * too-permissive factory methods from ImmutableMultiset.
