there is no public base class for notifier drivers

[Doug Hellmann]

While investigating a request for help with creating a custom notification driver [1], I noticed that even the base class for those drivers is private. We should provide some information about how to create your own notifier, and making the base class public seems like one easy way to start. We should also describe it explicitly in the documentation, maybe using the docstring for the driver base class.

Is this just a matter of making the classes "public" or are you thinking the driver interface needs more thought + solidifying before making something extendable?

... Perhaps I can donate a cycle or 2 to get this in.

    Allow custom notification drivers

    Our class hierarchy hides classes and modules that so its hard
    for folks to write a custom Notification driver. We should
    make these public and document them
