orxonox/branches/bezierTrack: moved Curve to its own file. I expect this class to be bigger than I thought at the beginning:
- Class Curve and its subclasses:
a) BezierCurve
b) closedBezierCurve
c) Nurbs
d) any other curve that might occure
this will take some time and many hours of thinking so please help
