This function calculates the groundwater head of an aquifer system according to the Gauss-Seidel iteration and Crank-Nicolson method (Wang & Anderson).
flowCondition indicates whether cells are either inactive (0), active (1) or have a constant head (2).
tolerance specifies the maximum difference between the current elevation and the new elevation.
