Store payload data for 1 voxel, 3 faces, 3 edges and 1 vertex at each

index triplet. Extend the voxel grid by one index in each dimension

to have "phantom voxels" to store the remaining elements in. Done.

All elements of a cell can be visited by increasing some of the three

indices by one. E.g. the bottom face of the cell at [i][j][k] is the

top face at [i+1][j][k], and the bottom-right-back vertex would be the

one at [i+1][j+1][k+1]
