/**
*   This decorator actually just adds the functionality to read the
*   test-suite classes from a given directory and instanciate them
*   automatically, use it as given in the example below.
*
*   usage example
*   <code>
*   $gui = new PHPUnit_GUI_SetupDecorator(new PHPUnit_GUI_HTML());
*   $gui->getSuitesFromDir('/path/to/dir/tests','.*\.php$',array('index.php','sql.php'));
*   $gui->show();
*   </code>
*   The example calls this class and tells it to:
*       find all file under the directory /path/to/dir/tests
*       for files, which end with '.php' (this is a piece of a regexp, that's why the . is escaped)
*       and to exclude the files 'index.php' and 'sql.php'
*   and include all the files that are left in the tests.
*   Given that the path (the first parameter) ends with 'tests' it will be assumed
*   that the classes are named tests_* where * is the directory plus the filename,
*   according to PEAR standards.
*   So that:
*       'testMe.php' in the dir 'tests' bill be assumed to contain a class tests_testMe
*       '/moretests/aTest.php' should contain a class 'tests_moretests_aTest'
