Auxiliary class for argument types (Trait-template class )
Is used to pass doubles by value, and arbitrary objects by const reference. This is TWICE as fast (2 x less memory access) and avoids bugs in VC6++ concerning the assignment of the result of intrinsic functions to const double&-typed variables, and optimization on.
