+ * @class Ext.util.DelayedTask
+ * Provides a convenient method of performing setTimeout where a new
+ * timeout cancels the old timeout. An example would be performing validation on a keypress.
+ * You can use this class to buffer
+ * the keypress events for a certain number of milliseconds, and perform only if they stop
+ * for that amount of time.
+ * @constructor The parameters to this constructor serve as defaults and are not required.
+ * @param {Function} fn (optional) The default function to timeout
+ * @param {Object} scope (optional) The default scope of that timeout
+ * @param {Array} args (optional) The default Array of arguments
