/**
 * Small Pest addition by Egbert Teeselink (http://www.github.com/eteeselink)
 *
 * Pest is a REST client for PHP.
 * PestJSON adds JSON-specific functionality to Pest, automatically converting
 * JSON data resturned from REST services into PHP arrays and vice versa.
 * 
 * In other words, while Pest's get/post/put/delete calls return raw strings,
 * PestJSON return (associative) arrays.
 * 
 * In case of >= 400 status codes, an exception is thrown with $e->getMessage() 
 * containing the error message that the server produced. User code will have to 
 * json_decode() that manually, if applicable, because the PHP Exception base
 * class does not accept arrays for the exception message and some JSON/REST servers
 * do not produce nice JSON 
 *
 * See http://github.com/educoder/pest for details.
