    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.
