Updated WatchPosition example
Updated WatchPosition example

The 'coords' property of $geolocation.position gets assigned again with every update so '$scope.myCoords = $geolocation.position.coords;' doesn't update when location changes. Causing confusions for new people including myself. So I changed the example for  `watchPosition` so new people won't get confused anymore.
