+It can take up 2 to 3 arguments. start, end and accuracy can be defined in the same as in getDistance.

+Return value is always float that represents the distance in meters.

+<h3>geolib.getRhumbLineBearing(object originLL, object destLL)</h3>
+
+Gets rhumb line bearing of two points. Find out about the difference between rhumb line and
+great circle bearing on Wikipedia. Rhumb line should be fine in most cases:
+
+http://en.wikipedia.org/wiki/Rhumb_line#General_and_mathematical_description

+Function is heavily based on Doug Vanderweide's great PHP version (licensed under GPL 3.0)
+http://www.dougv.com/2009/07/13/calculating-the-bearing-and-compass-rose-direction-between-two-latitude-longitude-coordinates-in-php/

+<h3>geolib.getCompassDirection(object originLL, object destLL, string bearingMode (optional))</h3>
+
+Gets the compass direction from an origin coordinate (originLL) to a destination coordinate (destLL).
+Bearing mode. Can be either circle or rhumbline (default).
+Returns an object with a rough (NESW) and an exact direction (NNE, NE, ENE, E, ESE, etc).
