CHANGED: project settings CrystalMeshTest:
- GoogleTest ist compiled directily by its source files (no lib to be linked)
- CrystalMeshLib is linked by  lib into CrystalMeshTest
- g++ is set to c++11 standart (Flag "-std=c++0x")

ADDED: 

First tests, to see if it works.
DELTED: Example files
FIXED: need to write namespace {...
} explicitly instead og using namespace ...

I think, this is a difference to the ms-compiler
