  UpdateFacebookStatus

  Demonstrates sending a Facebook status update using Temboo from an Arduino Yun.

  Check out the latest Arduino & Temboo examples and support docs at http://www.temboo.com/arduino

  A Temboo account and application key are necessary to run all Temboo examples.
  If you don't already have one, you can register for a free Temboo account at
  http://www.temboo.com

  In order to run this sketch, you'll need to register an application using
  the Facebook dev console at https://developers.facebook.com/apps -- after creating
  the app, log in to Temboo and visit https://www.temboo.com/library/Library/Facebook/Publishing/SetStatus/
  to use our OAuth Wizard (or OAuth Choreos) to obtain a Facebook access token.
  Substitute your access token for the placeholder value of FACEBOOK_ACCESS_TOKEN below.

  This example assumes basic familiarity with Arduino sketches, and that your Yun
  is connected to the Internet.

  Want to use another social API with your Arduino Yun? We've got Twitter, Google+,
  Instagram, Tumblr and more in our Library!

  This example code is in the public domain.

  IMPORTANT NOTE: TembooAccount.h:

  TembooAccount.h is a file referenced by this sketch that contains your Temboo account information.
  You'll need to edit the placeholder version of TembooAccount.h included with this example sketch,
  by inserting your own Temboo account name and app key information. The contents of the file should
  look like:

  #define TEMBOO_ACCOUNT "myTembooAccountName"  // your Temboo account name
  #define TEMBOO_APP_KEY_NAME "myFirstApp"  // your Temboo app key name
  #define TEMBOO_APP_KEY  "xxx-xxx-xxx-xx-xxx"  // your Temboo app key

  You can find your Temboo App Key information on the Temboo website,
  under My Account > Application Keys

  The same TembooAccount.h file settings can be used for all Temboo SDK sketches.

  Keeping your account information in a separate file means you can share the main .ino file without worrying
  that you forgot to delete your credentials.
