  ReadATweet
  Demonstrates retrieving the most recent Tweet from a user's home timeline 
  using Temboo from an Arduino Yún.
  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 Twitter dev console at https://dev.twitter.com. After creating the 
  app, you'll find OAuth credentials for that application under the "OAuth Tool" tab. 
  Substitute these values for the placeholders below. 
  This example assumes basic familiarity with Arduino sketches, and that your Yún
  is connected to the Internet.
  Want to use another social API with your Arduino Yún? We've got Facebook,
  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.
