This module implements the index, used for the mesh points.
Octopus uses an intermediate mesh with integer-valued coordinates, which then is scaled to the actual mesh. This module provides functions which perform the mapping between this integer-valued mesh and the point index. Besides a simple cubic indexing, also indexing using a spacefilling Hilbert curve is implemented.
