MPL arithmetic types should model the MPL Integral Constant concepts as 
specified here:

http://www.boost.org/doc/libs/1_43_0/libs/mpl/doc/refmanual/integral-constant.html

the idea is just to have your rational type being usable like:

boost::mpl::plus<R1,R2>::type

instead of using ratio_plus etc...
