Use with SceneKit

In order to make as little dependence as possible, Smooth.swift does not use SceneKit, but in order to make it easy to use it, a VectorType is added. Since SCNVector3 and SCNVector4 are concrete types already implementing VectorType, you can use VectorInterpolator by simply specifying it with extension.

extension SCNVector3: Vector3, VectorType {}
extension SCNVector4: Vector4, VectorType {}

VectorInterpolator is generated by providing Interpolator which interpolates for each element.

VectorInterpolator(points: [SCNVector3(0.1, 0.2, 0.5), SCNVector3(0.5, 0.6, 0.1)], interpolatorCreator: { LinearInterpolator(points: $0).interpolate })
