Write the Eq and Ord impls for TreeMap in a more straightforward way using iterator::Zip
Write external iterators for Difference, Sym. Difference, Intersection
and Union set operations.
These iterators are generic insofar that they could work on any ordered
sequence iterators, even though they are type specialized to the
TreeSetIterator in this case.
Looking at the `check` function in the treeset tests, rustc seems
unwilling to compile a function resembling::
fn check<'a, T: Iterator<&'a int>>(... )
so the tests for these iterators are still running the legacy loop
protocol.
Implement reverse iterators for TreeMap and TreeSet, that produce the keys in backward order.
.each_key(), .each_value() and the other methods are replaced by .iter() and .rev_iter(), and restrictions of those iterators.

Root out the last of all
each_*methods and the set operation methods (exceptmutate_valuesthat does live on).Implement a gang of iterators for difference, sym difference, intersection, union of two sets. Also implement
.rev_iter()for the map and the set.
