'make install' fails due to missing headers for example
calling 'make install' fails as it can not find some files in sub dir example.
I'm willing to fix this but i'm not sure about the parameter files.
@stefan.girke, @robert.kloefkorn should all the parameter files be installed? The way of including parameter files in fem-dg looks a little bit fishy to me. Could give me some guidance on the parameter files?
