new GeoPoint()
The GeoPoint object represents a physical location.
For example:
```js
var loopback = require(‘loopback’);
var here = new loopback.GeoPoint({lat: 10.32424, lng: 5.84978});
```
Embed a latitude / longitude point in a model.
```js
var CoffeeShop = loopback.createModel('coffee-shop', {
location: 'GeoPoint'
});
```
You can query LoopBack models with a GeoPoint property and an attached data source using geo-spatial filters and
sorting. For example, the following code finds the three nearest coffee shops.
```js
CoffeeShop.attachTo(oracle);
var here = new GeoPoint({lat: 10.32424, lng: 5.84978});
CoffeeShop.find( {where: {location: {near: here}}, limit:3}, function(err, nearbyShops) {
console.info(nearbyShops); // [CoffeeShop, ...]
});
```

Methods
distanceTo(point)
Determine the spherical distance to the given point.
Example:
```js
var loopback = require(‘loopback’);
var here = new loopback.GeoPoint({lat: 10, lng: 10});
var there = new loopback.GeoPoint({lat: 5, lng: 5});
loopback.GeoPoint.distanceBetween(here, there, {type: 'miles'}) // 438
```
