 * Humble HTTP Agent extension for SimplePie_File\r
 * \r
 * This class is designed to extend and override SimplePie_File\r
 * in order to prevent duplicate HTTP requests being sent out.\r
 * The idea is to initialise an instance of Humble HTTP Agent\r
 * and attach it, to a static class variable, of this class.\r
 * SimplePie will then automatically initialise this class\r
