+ * Throttle execution of a function. Especially useful for rate limiting

+ *                                    after the last throttled-function call. (After the throttled-function has not been called for `delay` milliseconds,
+ *                                    the internal counter is reset)
+ * @param  {Function}  callback       A function to be executed after delay milliseconds. The `this` context and all arguments are passed through, as-is,
+ *                                    to `callback` when the throttled-function is executed.
+ * @param  {Boolean}   debounceMode   If `debounceMode` is true (at begin), schedule `clear` to execute after `delay` ms. If `debounceMode` is false (at end),
+ *                                    schedule `callback` to execute after `delay` ms.
