Shifted CI stuff into seperate folder. Created own source and receiver files for test example. Changed some file names for better consistency.

Changes some variables to be more consistent.

I removed the possibility to create a single source directly within the configuration file. From now on it is requiered to provide a sourcefile, which can be generated by an included matlab routine.

This allows to read file paths, which include the / character.

No backward compatibility to LAMA versions older than 29.09.2016, due to change within the methods of dmemo::BlockDistribution.
