geo-convex-hull
===========
This module provides a function to determine the convex hull for a set of geographical coordinates (latitude and longitude). Units should be in degrees.

The return value is an array of latitude and longitude coordinates.

Example

``javascript
var calculateConvexHull = require('geo-convex-hull')

var points = [
{
latitude: 33.4255,
longitude: -111.9400
},
{
latitude: 43.6187,
longitude: -116..2146
},
{
latitude: 39.8066,
longitude: -101.0421
}
]

var convexHull = calculateConvexHull(points);
