I have not thought much; first thing that comes to mind is:

------ns3modulegen_node.py----------

def register_types(root_module):
    ...

def register_functions(root_module):
    ...


------ns3modulegen_wifi.py----------

def register_types(root_module):
    ...

def register_functions(root_module):
    ...


------ns3modulegen.py (main file)----------
import ns3modulegen_node
import ns3modulegen_wifi
...

def register_types(module):
    ns3modulegen_node.register_types(module)
     ns3modulegen_wifi.register_types(module)
    ...

def register_functions(module):
    ns3modulegen_node.register_functions(module)
    ns3modulegen_wifi.register_functions(module)
    ...

def main():
    out = FileCodeSink(sys.stdout)
    root_module = module_init()
    register_types(root_module)
    register_methods(root_module)
    register_functions(root_module)
    write_preamble(out)
    root_module.generate(out)


This structure does not allow local customization files.  I would have to
think better about that...  Perhaps something involving "try: import
ns3modulegen_wifi_local except ImportError: pass", i.e. if a xxx_local.py
file is found, use it, else ignore it.  Details to be figured out at
implementation time (thinking in abstract is harder).
