* # Create a instance of the object
* # Define the input and output files
* # Optional: Set one or more Filter. They are processed in LIFO order (last in, first out)
* # Process the file
* # Get it, save it or show it.
*
* <code>
* $oToken = new PHP_Beautifier(); // create a instance
* $oToken->addFilter('ArraySimple');
* $oToken->addFilter('ListClassFunction'); // add one or more filters
* $oToken->setInputFile(__FILE__); // nice... process the same file
* $oToken->process(); // required
* $oToken->show();
* </code>
