If the package does not import its modules or subpackages in __init__.py,  
you'll have to inspect the __path__ attribute and enumerate .py files.  
Then, try to load them and find all classes.
Warning: There is no way to tell if a certain module is intended to be  
imported at all or not (might be a test module, an unimplemented feature,  
a leftover from previous versions, a script intended to be run from the  
command line...)
You can use the inspect standard module (mainly getmembers() and  
isclass()) to find all classes; remember to filter by the class __module__  
attribute (else you'll get  imported classes too).
