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