More measurement units

Can you handle more measurement units being sent? Specifically: inches, feet, meters, centimeters.

Also, would be nice if kilometers was the default.

Thanks!

Tests?

Do you have a test suite?

LICENSE?

you need to add the license text for the mit license. For example, grab the text from http://opensource.org/licenses/MIT

Standard project files

Keep a changelog

I see that an update was released a few hours ago but there is no changelog. Not sure if you haven't had a chance to write one yet, if so then please disregard this.

Some tips here: http://keepachangelog.com/en/1.0.0/ ...doesn't need to be very elaborate, even basic descriptions of the changes should suffice. If you don't want to commit a separate file then at least documenting them in the GitHub releases would be helpful.

License

Another thing that I noticed was the lack of license file (apart from the "MIT License" link at the bottom of the readme). I suggest adding one so that people browsing the repo on GitHub can quickly identify the license of the project (more info here: https://github.com/blog/2252-license-now-displayed-on-repository-overview)

Great package by the way, I use it along with the HTML5 Geolocation API for a small feature in an application I develop at work.

Question: are this formulae correct?

So we have
var a = Math.sin(dLat/2) * Math.sin(dLat/2) +

that is the same as Math.sin(dLat/2) * 2 +, so what is the point of calculating twice?

Add eslint

Enforce linting and code style.
