    \brief Meta-function that takes a boost::variant type and tries to minimize
        it by doing the following:
        - if there's any duplicate types, remove them
        - if the result is a variant of one type, turn it into just that type
    \ingroup utility
    \par Example
    \code
        typedef variant<int, float, int, long> variant_type;
        typedef compress_variant<variant_type>::type compressed;
        typedef boost::mpl::vector<int, float, long> result_types;
        BOOST_MPL_ASSERT(( boost::mpl::equal<compressed::types, result_types> ));

typedef variant<int, int, int> one_type_variant_type;
        typedef compress_variant<one_type_variant_type>::type single_type;
        BOOST_MPL_ASSERT(( boost::equals<single_type, int> ));
