+   \brief A routine that is able to create normals.
+   The algorithm does the following:
+   1. It calculates creates Vectors for each normale, and sets them to zero.
+   2. It then Walks through a) all the Groups b) all the Faces c) all the FaceElements
+   3. It searches for a points two neighbours per Face, takes Vecotrs to them calculates FaceNormals and adds it to the Points Normal.
+   4. It goes through all the normale-Points and calculates the VertexNormale and includes it in the normals-Array.
