Chapter5 executable

[esel-fliegen]

I think the executable instruction for Chapter5 should be, "./Chapter5 ../data/test.pgm" when inside the build dir. That's how I got it to work.

yes, in the documentation is not set the full path to segment, but you can choose any of the tree images that are in the data path. I will add a bit more of extra info in the readme to be more clear.
