  // e.g. saying "Show me Batman and Robin" will call showFlickr('Batman and Robin');
  'show me *tag': showFlickr,

  // A named variable is a one word variable, that can fit anywhere in your command.
  // e.g. saying "calculate October stats" will call calculateStats('October');
  'calculate :month stats': calculateStats,

  // By defining a part of the following command as optional, annyang will respond
  // to both: "say hello to my little friend" as well as "say hello friend"
