From #49 , we need mutable structures to allow users to interactively edit structures (via sliders or drag points in the UI). FlexSpline is an upcoming component of this: it will be a collection of moveable points that acts like a CubicSpline1D by calculating a new spline whenever it is asked for a value but at least one underlying point has changed. MovingPoint2D is the "moveable point" chunk of this.
