        Executes a given block using each point in a range with a distance step.
        Parameters:
        range - The parametric range to enumerate points in.
        distanceStep - The distance to step between points.
        block - The block to execute for each point. This block takes two parameters point The interpolated point on the spline. stop A reference to a Boolean value. Setting the value to YES within the block stops further enumeration of the array. If a block stops further enumeration, that block continues to run until it’s finished.
