CHECKMESHADJACENTFACES Check if adjacent faces of a mesh have similar orientation.

   checkMeshAdjacentFaces(VERTICES, EDGES, FACES)
   The functions returns no output, but if two faces share a common edge
   with the same direction (meaning that adjacent faces have normals in
   opposite direction), a warning is displayed. 
   
   Example
   [v e f] = createCube();
   checkMeshAdjacentFaces(v, e, f);
   % no output -> all faces have normal outwards of the cube

   v = [0 0 0; 10 0 0; 0 10 0; 10 10 0];
   e = [1 2;1 3;2 3;2 4;3 4];
   f = [1 2 3; 2 3 4];
   checkMeshAdjacentFaces(v, e, f);
      Warning: Faces 1 and 2 run through the edge 3 (2-3) in the same direction
