Range header field parser.

## Installation

This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):

```sh
$ npm install range-parser
```

## API

```js
var parseRange = require('range-parser')
```

### parseRange(size, header, options)

Parse the given `header` string where `size` is the size of the selected
representation that is to be partitioned into subranges. An array of subranges
will be returned or negative numbers indicating an error parsing.

* `-2` signals a malformed header string
  * `-1` signals an unsatisfiable range

```js
// parse header from request
var subranges = parseRange(size, req.headers.range)

// the type of the subranges
if (subranges.type === 'bytes') {
  // the ranges
  subranges.forEach(function (r) {
    // do something with r.start and r.end
  })
}
```

#### Options

These properties are accepted in the options object.

##### combine

Specifies if overlapping & adjacent subranges should be combined, defaults to
`false`. When `true`, ranges will be combined and returned as if they were
specified that way in the header.

```js
parseRange(100, 'bytes=50-55,0-10,5-10,56-60', { combine: true })
// => [
//      { start: 0,  end: 10 },
//      { start: 50, end: 60 }
//    ]
```
