Rbtree Marshalling Example

This example demonstrates sending and receiving objects stored in a Boost Intrusive rbtree. The Middle code is:

    message_manager
       (rbtree<Base>)
    }

base_ex.hh defines class named Base.
derived_ex.hh defines class named Derived.
message_manager.cg.hh has C++ Middleware Writer output.
message_manager.cg.cc has C++ Middleware Writer output.
rbtree_marshalling.cc puts the pieces together in a main().
