/** \struct boost::bimaps::tags::support::apply_to_value_type
\brief Higger order metafunction similar to mpl::apply but for tagged types.
\code
template< class Metafunction, class TaggedType >
struct apply_to_value_type
{
typedef tagged
<
Metafuntion< value_type_of< TaggedType >::type >::type,
tag_of< TaggedType >::type

\endcode
This higher order metafunctions is very useful, and it can be used with lambda
expresions.
