Just to summarize the design discussion from chat:

• each service gets a subpackage, containing any relevant handlers, objects, etc.
• handlers for restful API requests all go in service/apihandlers.py
• all other handlers related to the service go in service/handlers.py
• a handlers file shall have default_handlers, a list of tuples for the default URL / handler mapping used to register the handlers.

Looks like you need to update some test exclusions

After catching up the test exclusions, 👍 to merge.

So this does not change the URL scheme for now right ?
If so, good for me.

In a Google+ hangout today we decided to organize things in the following manner:

auth
    login.py
    logout.py
base
    handlers.py
    zmqhandlers.py
tree
    handlers.py
notebook
    handlers.py
services
    notebooks
        handlers.py
        azurenbmanager.py
        filenbmanager.py
        nbmanager.py
    clusters
        handlers.py
        clustermanager.py
    kernels
        handlers.py
        kernelmanager.py

To prevent this from becoming too deeply nested, we are going to move IPython.frontend.html.notebook to IPython.html.

OK this is ready for final review and merge. The PR follows the design posted above. Test suite passes and notebook runs, but someone should play with it a bit.

read, tested, and played with - looks good to me. 👍 to merge.
