+ * Decorator that makes a deferred "cancelable".  It adds a cancel() method that
+ * will call a special cancel handler function and then reject the deferred.  The
+ * cancel handler can be used to do resource cleanup, or anything else that should
+ * be done before any other rejection handlers are executed.
+ *
+ * Usage:
+ *
+ * var cancelableDeferred = cancelable(when.defer(), myCancelHandler);
