/**
 * Installs/Updates a test suite, runs the first MIDlet in the suite in a loop
 * specified number of iterations or until the new version of the suite is not
 * found, then removes the suite.
 * <p>
 * The MIDlet uses these application properties as arguments: </p>
 * <ol>
 *   <li>arg-0: URL for the test suite
 *   <li>arg-1: Used to override the default domain used when installing
 *    an unsigned suite. The default is maximum to allow the runtime API tests
 *    be performed automatically without tester interaction. The domain name
 *    may be followed by a colon and a list of permissions that must be allowed
 *    even if they are not listed in the MIDlet-Permissions attribute in the
 *    application descriptor file. Instead of the list a keyword "all" can be
 *    specified indicating that all permissions must be allowed, for example:
 *    operator:all.
 *    <li>arg-2: Integer number, specifying how many iterations to run
 *    the suite. If argument is not given or less then zero, then suite
 *    will be run until the new version of the suite is not found.
 * </ol>
 * <p>
 * If arg-0 is not given then a form will be used to query the tester for
 * the arguments.</p>
