Run the Shiny Application
A function that will be called before the app is actually run.
This is only needed for shinyAppObj, since in the shinyAppDir
case, a global.R file can be used for this purpose.
Named options that should be passed to the runApp call
(these can be any of the following: "port", "launch.browser", "host", "quiet",
"display.mode" and "test.mode"). You can also specify width and
height parameters which provide a hint to the embedding environment
about the ideal height/width for the app.
Can be one of "url", "server", or
"disable". The default value, NULL, will respect the setting from
any previous calls to  enableBookmarking(). See enableBookmarking()
for more information on bookmarking your app.
