/* CODE SAMPLE: GETTING WEATHER OBSERVATIONS FOR A FIELD LOCATION */
// Include Header
// Be sure to change the variables in this header.php file, especially adding your
// API Key and Secret or else the API calls will not run. This file uses three helper
// functions--GetOAuthToken(), makeAPICall(), and parseHTTPHeaders()--to streamline
// basic API operations.

// function (in header.php) to streamline that part

//the function throws an exception which we can catch to fail gracefully.
