	/// <remarks>
	/// Log4net is capable of outputting extended debug information about where the current 
	/// message was generated: class name, method name, file, line, etc. Log4net assumes that the location
	/// information should be gathered relative to where Debug() was called. In IBatisNet, 
	/// Debug() is called in IBatisNet.Common.Logging.Impl.Log4NetLogger. This means that
	/// the location information will indicate that IBatisNet.Common.Logging.Impl.Log4NetLogger always made
	/// the call to Debug(). We need to know where IBatisNet.Common.Logging.ILog.Debug()
	/// was called. To do this we need to use the log4net.ILog.Logger.Log method and pass in a Type telling
	/// log4net where in the stack to begin looking for location information.
