    defined by the major directions {u0,u1} (unit {n}-vectors) and the
    respective radii {urad0,urad1}.
    
    If if {box} is true, the plot domain is the rectangle {\RC}. If
    {box} is false the plot domain is an ellipse {\RF} IN both cases the
    center of the domain will be at the origin of {\RR^n}, its main
    directions will be {u0} and {u}, and its radii along those
    directions will be {urad0} and {urad1}.
    
    Namely, enumerates a grid of points with increment {step} on the
    plane defined by {u0} and {u1}. For each sample point
    {(s0*u0,s1*u1)} of that grid that lies inside the plot domain,
    computes the corresponding vector {v = s0*u0 + s1*u0} and writes to
    {wr} a line with {s0}, {s1}, and the goal function {F(n,v)}.*/
