Position to number conversion methods
getXXXNumber methods enable the user to convert an position into a global number in the array. Axis [1,2,3] means one of directions: along i, j or k. For cell constituents (FACE or EDGE), Axis selects one of those having same : a FACE which is normal to direction along given Axis; an EDGE going along given Axis. Exception for Axis out of range. For 2D grids, k is a dummy argument.
