  Retrieves JSON data from Moves (http://www.moves-app.com/),
  from a provided start date until the current date. Days for
  which a data file already exists are skipped.

  Requires a Moves access token, which can be obtained using the
  web interface set up by Nicholas Felton for his MovesMapper 
  project. See instructions below. 
 
  NOTE: Try to get the starting date as close as possible to a
  valid date for which you have Moves data. The code will give 
  nasty-looking errors for any date that has no data.
  
  API code based on MovesMapper by Nicholas Felton:

// Instructions from original code by Nicholas Felton. We'll 
// get a valid Moves access token by using his web service interface.
// ------------------------------------------------------------------
// SETUP
// 1. Open Moves app and make sure that your activity is up to date.
// 2. In the settings, go to the Apps section and click the add a PIN button.
// 3. Visit http://shielded-sierra-8807.herokuapp.com to get the PIN and enter this in the app.
// 4. Once you've given the app permission to access your data, the web page will refresh and dislay your access token.
// 5. Set the accessToken string 
// 6. Run the sketch.
