MESHFACECENTROIDS Compute centroids of faces in a mesh.

   CENTROIDS = meshFaceCentroids(VERTICES, FACES)
   VERTICES is a set of 3D points  (as a N-by-3 array), and FACES is
   either a N-by-3 index array or a cell array of indices. The function
   computes the centroid of each face, and returns a Nf-by-3 array
   containing their coordinates.

   Example
     [v, e, f] = createIcosahedron;
     normals1 = meshFaceNormals(v, f);
     centros1 = meshFaceCentroids(v, f);
     figure; hold on; axis equal; view(3);
     drawMesh(v, f); 
     drawVector3d(centros1, normals1);
