 * Creates a debounced function that delays invoking `func` until after `wait`
 * milliseconds have elapsed since the last time the debounced function was
 * invoked. The debounced function comes with a `cancel` method to cancel
 * 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`.

	     * Lazy evaluation allows several methods to support shortcut fusion.
	     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
	     * the creation of intermediate arrays and can greatly reduce the number of
	     * iteratee executions. Sections of a chain sequence qualify for shortcut
	     * fusion if the section is applied to an array and iteratees accept only

	     * fusion is subject to change.
	     *
	     * Chaining is supported in custom builds as long as the `_#value` method is
	     * directly or indirectly included in the build.

	     * 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
	     * throttled function. Subsequent calls to the throttled 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 throttled function
	     * is invoked more than once during the `wait` timeout.
