added the SimpleFile class to the sample library to check how a

method returning a boolean value that indicates success/failure
on a IO operation could be modified to express the any occurring
problems as Python exceptions (in this case IOError);
the generator was changed to return a 'None' value for Python
callers on methods that had it's return value removed
