Dear Marcus,

Thank you for evaluating the Boost.RangeEx submission.

The RangeEx submission has had inputs from many others, including Eric
Neibler who is unfairly missing an acknowledgement in my current
documentation. I need to address this. Thorsten has continually helped
evaluate the various versions of RangeEx too.

These are definately missing. I have a bit of a problem here, there are
several algorithms I would like to include that are already in
<boost/detail/algorithm.hpp>. Before a release I will need to remove any ODR
violations when these headers are included together with range.  This
currently defines container_contains that behaves like a 'contains' function
would. I will coordinate and address a solution before release.
