iterator_adaptor update

Please check out the following on the iterator_adaptor_update branch:

boost/counting_iterator.hpp
boost/iterator_adaptors.hpp
boost/token_iterator.hpp
libs/utility/iterator_adaptor_test.cpp
libs/utility/iterator_traits_test.cpp

These represent changes we've been meaning to make:

1. Remove less() from policies
2. Policies operate on whole iterator_adaptor<>s rather than Base type

These shouldn't be checked into the main trunk before Jeremy gets a chance
to update the graph library, but the changes pass all tests and should work
for you.

The documentation still needs to be updated.

Regards,
Dave
