A simple log adapter that writes messages to files. By default, messages are written to
`resources/tmp/logs/<type>.log`, where `<type>` is the log message priority level.				
{{{
use lithium\analysis\Logger;

Logger::config(array(
	'simple' => array('adapter' => 'File')
));
Logger::write('debug', 'Something happened!');
}}}

This will cause the message and the timestamp of the log event to be written to
`resources/tmp/logs/debug.log`. For available configuration options for this adapter, see
the `__construct()` method.
