Script logging infrastructure is redundant with python logging module

[Francis J. Lacoste]

The script log infrastructure builds redundant infrastructure around the standard Python logging infrastructure.

Its log() function should be deprecated to use the logging module infrastructure directly.

The logger() function creates a child logger based on the script name (usually), but then code wanting to use that logger should use the non-standard log() function or obtain a logger by name (which violates encapsulation).

So logger() should configure the root logger.
