shared_container_iterator now uses std::shared_ptr to store the reference to the container. boost::shared_ptr is still supported and is wrapped into std::shared_ptr on construction, so there is overhead due to allocation of std::shared_ptr state. Going forward, std::shared_ptr is expected to be the primary use case. As a bonus, this eliminates the dependency on Boost.SmartPtr. Moved shared_container_iterator.hpp into the iterator directory and left a forwarding header for backward compatibility.
