logging module usage

[mennis]

I am working on a library for controlling various appliances in which
I use the logging module.  I'd like some input on the basic structure
of what I've done.  Specifically the logging aspect but more general
comments are welcome.  I'm convinced I mis-understand something but
I'm not sure what.  I've posted a version of the library at github.
