3.6. Forces

Forces are now part of the extras_mod, so to add forcing take a copy of extras/extras_mod.f90 into the experiment/xxx/ dir, and uncomment the lines marked … ! forces

The new forces_mod does NOT collide with the old force_mod modules, so for compatibility one can construct new forces_mod modules by using force%selected to load values into patch%force_per_unit_mass.

However, in the future forces_mod.f90 files should be written directly, since this alleviates the need to stick to a definitive (and long) argument list for the force%selected functions.
