viikko2-feedback

-Once again, not sure whether I should be writing the feedback into here ^^; Did I "create" the pull request last time?
-Either way, the exercises seem to have been slightly simpler this time around, compared to last week - unless I've done them all wrong, of course :D 
-Also, wasn't sure whether I should be saving the netbeans exercises straight into the ohtu2014 (forked repository) or if I needed to save everything in the new private repository for this week (in my case, ohtu-viikko2-2014). So I basically did both (sorry about that! :/)
-Will need to read up more on the usefulness of Spring. I understood from the exercise's name that it was supposed to make the code cleaner but I am not certain that was the case.
