Super [tiny](./index.js), dependency-free wrapper to make promises lazy, i.e. sit there like a potato until `.then()` is invoked.

Assumes native promises, or at least `Promise` on the global scope (`global` or `window`).

### Installation

```bash

$ npm i -S potato-promise

```

### Usage

```javascript

const Potato = require('potato-promise')

const p = new Potato((resolve) => {

  console.log(3)

  resolve()

})

console.log(1)

setTimeout(() => {

  console.log(2)

  p.then(() => {}).catch(() => {})

}, 1000)

// > 1

// ...after 1 second...

// > 2

// > 3

```

__Note:__ I'm only using `new` here for familiar semantics; this is actually

a factory function. The following would also work...

```javascript

Promise.lazy = require('potato-promise')

const p = Promise.lazy((resolve) => ...)

```
