Turn arrays into smooth functions.

Interpolation functions are ported from [Smooth.js](https://github.com/osuushi/Smooth.js/).

## Installation

### CocoaPods

```ruby

pod 'Smooth'

```

### Carthage

```

github "ryohey/Smooth.swift"

```

## 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.

```swift

extension SCNVector3: Vector3, VectorType {}

extension SCNVector4: Vector4, VectorType {}

```

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

```swift

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

```
