Recent modifications in the HOBO mesh

In its original formulation the two-dimensional free-Lagrangian hydro code HOBO used massless tracer points without a mesh. Later we changed to a median mesh with all quantities cell centered. Now we have shifted pressure to the cell vertices resulting in a staggered mesh in velocity and pressure.
