4 point sigmoidal elliptical curve

H and J are used to smoothly blend from one elliptical parameterization to another to produce the curve... the final curve is parameterized over [-pi/2] to [pi]... It might be good for something like designing fonts because it can do circular arcs that are found in a lot of letters well that bezier splines don't manage very well...
