Logging

Detailed Description

The logging framework offers an efficient, extensible system to log messages from programs with multiple threads to a number of channels. Logging can be completely disabled at compile time, when the logging macros are used. At runtime, log messages are filtered by a level of severity. Filtering is very efficient, because log messages are not even built if their log level is too low. Currently three types of output channels exist, logging to files with file rolling, to the console and to the serial port. The logging framework can be extended by new channels.
