// This sets up alternative dialog boxes. They mostly work the same way as
// their UI counterparts, expect instead of returning the result, a callback
// needs to be included that returns the result as its first parameter.
// In the future we may want to add additional types of dialog boxes, since 
// they should be easy to handle this way.
