Now we sort the failure causes based on how many builds have failed
Now we have another structure, but there is some things to improve. Will
do so in the following commits.
Now the class structure and the methods are clearer. The sorting
still works as it should.
Now we have a list of the most common failure causes
Now we have a functional list of top failure causes
Now it is possible to decide how many of the top failure causes that
should be displayed in the presentation page.
Added a java-file for failure builds.
