extracts the M, P and T parameters from a NACA 4 digit code.
given a point xc along the camber line, returns pairs
(xu,yu) and (xl,yl) along the upper and lower airfoil surface
of a NACA cambered 4-digit airfoil.
given a point x, returns the value y(x) so that (x,y(x))
lies on the upper surface of a NACA symmetric 4-digit airfoil
and (x,-y(x)) lies on the lower surface.
