Subject: * rename new Quat class to Quaternion, remove existing Quaternion *
 add Copyright line for Mathieu * cast() was broken (compile errors) and
 needed anyway to be in QuaternionBase * it's VectorBlock<T,3>, don't pass
 additional parameter 1, it has different meaning!! * make it compile with GCC
 (put 'typename' at the right location)
