* GTK GUI interface for PHPUnit.

* This class is a PHP port of junit.awtui.testrunner. Documentation
* for junit.awtui.testrunner can be found at
* http://junit.sourceforge.net
*
* Due to the limitations of PHP4 and PHP-Gtk, this class can not
* duplicate all of the functionality of the JUnit GUI. Some of the
* things this class cannot do include:
* - Reloading the class for each run
* - Stopping the test in progress
*
* To use simply intantiate the class and call main()
* $gtk =& new PHPUnit_GUI_Gtk;
* $gtk->main();
*
* Once the window has finished loading, you can enter the name of
* a class that has been loaded (include/require some where in your
* code, or you can pass the name of the file containing the class.
*
* You can also load classes using the SetupDecorator class.
