Subject: [PATCH] Add missing includes, switch to min_category, add iterators
 namespace.

Add missing includes for Boost.Iterator and standard library components.
Specifically, enable_if_convertible in Boost.Iterator is now defined
in its own header.

Use min_category instead of minimum_category as the latter is deprecated.
The replacement is a direct equivalent, but doesn't bring the dependency
on Boost.MPL and is variadic.

Explicitly specify iterators namespace for Boost.Iterator components.
