Add a functionnal Ajax module
Calculate distance and direction, ajax callbacks

Add ajax callback for success --
Calculate distance from user
If user is close to ISS, calculate cardinal direction from user and write message
setISS function

On success, set ISS options on user object
Add a user

  * User can get his/her location
    * Only updates if the coordinates are stale
      * Currently more than five minutes old
  * Can find and set its own coordinates
  * Has an ISS object
    * Displays whether the ISS is visible
    * Displays which direciton the ISS is from user

Issues:
  * API call to get location is asynchronous. After the call,
  the user coordinates are returned. However, the API call
  has not yet finished at that point, so the coordinates are
  always one getLocation call behind
  * This should not matter much, as the maximum time will likely
  be about 5 minutes
Move file to the pebble-js-app.js

Add timer to send message to phone.

Polls the phone every 60 seconds. We do this to routinely ask
the ISS api for current location. Pebble does not recommend using
setInterval in js to routinely poll. They recommend setting a timer
on the watch.
Integrate pebble watch messaging to poll ISS api.
