		* delayed `func` invocations and a `flush` method to immediately invoke them.
		* Provide `options` to indicate whether `func` should be invoked on the
		* leading and/or trailing edge of the `wait` timeout. The `func` is invoked
		* with the last arguments provided to the debounced function. Subsequent
		* calls to the debounced function return the result of the last `func`
		* invocation.
		*
		* Note: If `leading` and `trailing` options are `true`, `func` is
		* invoked on the trailing edge of the timeout only if the debounced function
		* is invoked more than once during the `wait` timeout.
		*
		* If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
		* until to the next tick, similar to `setTimeout` with a timeout of `0`.
