streamify-string
================
`streamify-string` accepts a `string` and returns a [Readable stream][] that
outputs the string. It's useful for stubbing Readable streams when writing
unit-tests for [Writeable][], [Duplex][], and [Transform][] streams.
```javascript
const Streamify = require('streamify-string');
const myWritableStream = require('../path/to/file.js');
// initialize a string
var str = 'Grumpy wizards make toxic brew for the evil Queen and Jack.'
// "Streamify" that string and pipe it to a writeable stream
Streamify(str).pipe(myWriteableStream);
```
### Parameters ###
```javascript
const streamified = Streamify(str, [options]);
```
- `str`: the `string` that the stream should output.
- `options`: Optional options to pass to the stream constructor. ([Documentation][options])
### Events ###
The stream will emit the following events:
- [`readable`][event-readable]
- [`data`][event-data]
- [`end`][event-end]
- [`close`][event-close]
