Pressure and wind

[eranimo]

Requires #2

Pressure can be determined with Temperature and Moisture

Wind can be determined by the difference in pressure in each cell with respect to its neighbors. Each cell would get a magnitude (difference in pressure) and direction (composed of all neighbor vectors).

Coriolis effect on air circulation will need to be taken into account when determining wind direction.
