/**
 * Launch a dialog for getting a local file or a URL in order to import
 * content.  If a URL is chosen, download the content ensure that the public
 * file member points to it.  The URL must be resolvable and return a response
 * code of 200 in order for this to work.  In the case where the file's content
 * comes from a URL, it will request deleteOnExit().
 *
 * When this dialog closes, if file is null, it was canceled.
 * If it was not canceled, file will point to the content.
 * If url is not null, it means the import occurred from a url and that
 * is the source.
