  sc_nbexterns.h -- External functions for both sc_signed and sc_unsigned
                    classes. These functions work on two parameters u and
                    v, and copy the result to the first parameter u. This
                    is also the reason that they are suffixed with _on_help.
 
                    The vec_* functions are called through either these
                    functions or those in sc_nbfriends.cpp. The functions in
                    sc_nbfriends.cpp perform their work on two inputs u and v,
                    and return the result object.
