The logging manager
Singleton
class.The logger manager can be included as a member to any class to manager logging of information. Each logger is identified by the module id (mid), with which the logger settings can be changed.
By default a logger with log level LOG_INFO that is output to the stdout is created.

Examples
>>> from mlpy.tools.log import LoggingMgr >>> logger = LoggingMgr().get_logger('my_id') >>> logger.info('This is a useful information.')
This gets a new logger. If a logger with the module id my_id already exists that logger will be returned, otherwise a logger with the default settings is created.
>>> LoggingMgr().add_handler('my_id', htype=LoggingMgr.LOG_TYPE_FILE)
This adds a new handler for the logger with module id my_id writing the logs to a file.
>>> LoggingMgr().remove_handler('my_id', htype=LoggingMgr.LOG_TYPE_STREAM)
This removes the stream handler from the logger with module id my_id.
>>> LoggingMgr().change_level('my_id', LoggingMgr.LOG_TYPE_ALL, LoggingMgr.LOG_DEBUG)
This changes the log level for all attached handlers of the logger identified by my_id to LOG_DEBUG.
