Some of the GPU routines for particles expect that each GPU has local particles present. These edits prevent GPU errors from occurring when a GPU does not have local particles. This is required for simulations that use COSMOLOGY & PARTICLES but do not have particles.
I have also added an Adiabatic Expansion ICs routine that initializes a simple adiabatic expansion test based on the Zeldovich pancake ICs. When the velocities are set to zero in this set of ICs, the uniform gas distribution will just expand (constant comoving density) and cool (T decreases with (1+z)^2/(1+z_init)^2)
