Nurbs CV have a weight too, but that attribute is not
shared by Bezier.
However, what could be done as far as class hierarchy
goes is this:

BPoint (for Poly Curve)
 | |
 | |
 | +- BNURBSPoint (for nurbs curve, with weight added)
 |
 +- BBezierPoint (for bezier, with handles)

BPoint would have x,y,z coordinates vector (Z unused
for IPOs) and tilt (also unused for IPOs).
BNURBSpoint would inherit that and add weight.
BBezier would add two handle vectors.

This would be a good place/time to reintroduce
Ascotan's vector/mathutils patch.
