Will call output callback if defined.

The purpose of this function is to directly emit messages, for instance
when the class is being used from shell scripts. If a valid callback
has been setup with @see setOutputCallback(), that method will be called
with <var>$message</var> and <var>$messageType</var>

@param string $message
@param string $messageType
@return void
Will call output callback if defined .
