Haversine formula in Javascript, in meters, nothing else

## Example

### Import

```javascript

const haversine = require('haversine-distance')

// or

import haversine from 'haversine-distance'

```

### Usage

```javascript

const a = { latitude: 37.8136, longitude: 144.9631 }

const b = { latitude: 33.8650, longitude: 151.2094 }

console.log(haversine(a, b)) // 714504.18 (in meters)

```

Alternative forms such as `lat`, `lng` and `lon` work too, with mixed support:

```javascript

const a = { lat: 37.8136, lng: 144.9631 }

const b = { lat: 33.8650, lon: 151.2094 }

console.log(haversine(a, b)) // 714504.18 (in meters)

```

### GeoJSON support

```javascript

const a = [144.9631, 37.8136]

const b = [151.2094, 33.865]

console.log(haversine(a, b)) // 714504.18 (in meters)

```
