Changing the log level from Python

[sirwart]

First of all, thanks for this excellent library. I've found it to be much easier to use than other robotics libraries for what I need (IK and FK).

I'm using the Python library and would like to change the log level, but haven't been able to figure out how to do that from Python. I'm using it in a library, so I don't want to have to put a log4cxx file in a standard location, but could put a file in my library if the config file location can be specified. If there's not a way to control the log level, do you have any recommendations on a high level approach to make that change?
