implemented exercise 2. Should almost be fine...only problem is transforming the points to the target image! Didn't get the image from the course site, since it is not online, thus I got the images from the exercise sheet. error_ellipse.m is also from the internet and not from the course site, since it isn't online either. So far so goood. I think the code should be fine, with the correct images... Check it out for yourself. Jeezy exerice, I guess ;)
