-        Marionette instance should wait during requests.
-
-        There are three types of timeouts that can be set: implicit,
-        script and page load.
-
-        * An implicit  timeout specifies the amount of time a Marionette
-        instance should wait when searching for elements. Here, marionette
-        polls a page until an element is found or the timeout expires,
-        whichever occurs first. When searching for multiple elements,
-        the driver should poll the page until at least one element is
-        found or the timeout expires, at which point it should return
-        an empty list.
-
-        * A script timeout specifies the amount of time the Marionette
-        instance should wait after calling executeAsyncScript for the
-        callback to have executed before returning a timeout response.
-
-        * A page load timeout specifies the amount of time the Marionette
-        instance should wait for a page load operation to complete. If
-        this limit is exceeded, the Marionette instance will return a
-        "timeout" response status.
