Added an example macro and shuffled IKarabo documentation to the end of the file.
I added a basic example to the howToMacro file and shuffled the order of the documents. I think that the rest is currently fine, it all seems correct based on my reading, but it might be worth someone else taking a look at it as well. I didn't comment on the fact that there are now multiple macro servers, but we could do so if you think it is relevant.
