Exports a tour as a JS file.
            You can call self.export_tour() anywhere where you would
            normally use self.play_tour() to play a tour.
            It will include necessary resources as well, such as jQuery.
            You'll be able to copy the tour directly into the Console of
            any web browser to play the tour outside of SeleniumBase runs.
            @Params
            name - If creating multiple tours at the same time,
                   use this to select the tour you wish to add steps to.
            filename - The name of the JavaScript file that you wish to
                   save the tour to.
