More carefully defined the concepts. That is the concept of the library is now clear: Trap at either compile or runtime integer operations which yield a result which differs from the normal arithmetic result. Pending on this check in: a) only addition is fixed up so far b) uses BOOST_TYPEOF... rather than decltype(... - final decision sill pending. c) comments out some compile time checks which should be re-instated. d) fixed tests so that they actually work!
