void MsgHandler::beginProcessMsg	(	std::string	msg,
		bool	addType = `true`
	)

Begins a process information.

When a longer action is started, this method should be used to inform the user about it. There will be no newline printed, but the message handler will be informed that a process message has been begun. If an error occurs, a newline will be printed. After the action has been performed, use endProcessMsg to inform the user about it.
