GRAVITY - Add gravity body forces

GRAVITY x_c y_c z_c g_x g_y g_z

The GRAVITY keyword allows the user to include the effects of gravity on the fluid.

x_c, y_c, z_c Coordinates of a point on the "ground" plane (normal to the gravity vector) used to define the location of zero potential energy, in grid units
g_x, g_y, g_z Components of the gravity vector, in ft/sec². For example, if the y direction is normal to the earth's surface, these values might be 0.0, -32.2, 0.0.
