[Users] Tracer particles: Processor distribution of array

[Erik Schnetter]

Jens

The "DISTRIB=..." options only determine on which process the particles are
held. This is a purely computational property and is independent of any
physics. You cannot change this without updating the time integration
algorithm.

The particles are set up via some kind of initial condition, and there
might be a run-time parameter that you can set to modify this.
