Determines azimuth (compass direction) & distance of the second point (B) as seen from the first point (A), given latitude, longitude & elevation of two points on the Earth

## Original Author
Moulded from [Don Cross](http://cosinekitty.com/)'s [Azimuth/Distance Calculator](http://cosinekitty.com/compass.html)

## Getting Started
Install the module with: `npm install azimuth`

```javascript
var calculate = require('azimuth');
calculate.azimuth({
