Create chaining APIs from functions

## Install

```bash

$ npm install new-chain

```

## Usage

```js

Num(3).sum(10).sub(5).mul(2).val()

// => 16

function Num(x){

    var x = 0

    var chain = newChain(sum, sub, mul) // or: { alias: mul, mul:mul } or: newChain({ alias: mul }, mul)

    chain.val = val

    return chain

    function mul(n){

        x *= n

    }

    function sum(n){

        x += n

    }

    function sub(n){

        x -= n

    }

    function val(n){

        return x

    }

}

```

### `from`

```js

x = [1, 2, 3]

val = newChain.from(x)(foo, bar)

val

// => [1, 2, 3]

val.foo().bar()

// => [1, 2, 3]

```
