/** \brief Gets a map view of a bidirectional map

Convertible to \c map_type_by<Tag,Bimap>::type
Instead of using \c map_type_by<Tag,Bimap>::type this functions use
\b Boost.call_traits to find the best way to return this value. To help
the user of this function the following metafunction is provided
\code

namespace result_of {

template< class Tag, class Bimap >
struct map_by( Bimap & b );

} // namespace result_of

\endcode

// Since it is very error-prone to directly write the hole bunch
// of relation accesor. They are buil from litle macro blocks that
// are both more readable, leading to self docummenting code and a
// lot more easier to understand and mantain.
// It is very important to note that the three building blocks have
// to laid in the same namespace in order to work. There is also
// important to keep them in order.
// The forward declaration are not necesary but they help a lot to
// the reader, as they undercover what is the signature of the
// result code.
// In the end, it is not quicker to do it in this way because you
// write a lot. But this code has no complexity at all and almost
// every word writed is for documentation.
