Read in a previously saved set of particles from a restart file. This allows continuation of a previous spatial simulation.
Only particle information is stored in the restart file. Thus before reading a restart file, you should re-define species and geometry information, and must setup bins via the bin command.
Because restart files are binary, they may not be portable to other machines.
The bin command must be used before reading a restart file.
This command can only be used for spatial simulations.
