We used customized header, for toggling the bullets on the API view only up to level 2. However, turned out, that this header is only compatible with this doxygen version. We should be independent of the doxygen version, therefore removed this approach again. Has to be discussed.

algorithms_cpp: unified behavior on empty input, added unit tests on empty and negative input ranges

Modify the create tarball script, to completely automate the tarball creation. Also add gitattributes file, to make git recognize this file as text (and not binary).
