/// This one is a tricky one. I will preface it by saying that for the most part you should not need this method.
/// Most Selenium methods (Click, Submit, FindElement, etc) use the implicit timeout to wait for an element to appear
/// and then wait until the page finishes loading before returning control back to your program. Usually if you feel
/// like you need to wait for the page to load, it is better to try adjusting the implicit wait time first or use the
/// WaitWebDriver class. Now, with those disclamers, sometimes it can be useful to have the ability to wait for the page
/// to finish loading.For example, SendKeys does not wait for the page to finish loading.
///
/// element.SendKeys(Keys.Enter);
/// driver.WaitForPageToLoad();
/// Same thing as
/// element.Click();
///
/// </summary>
