sim run Command

• Reads the config file, or some other machine-readable file generated by sim config, and issues the commands to actually run the simulations.
• Some mechanism for specifying ensembles versus individual run jobs is needed.
• The actual executable that is submitted should be a script that is custom-generated and given a project- or simulation-specific name. Something like:

#!/bin/sh
RUNJOBCOMMANDS
call sim restart

sim restart configures the job restart, first checking for appropriate stopping conditions, then submits the restart job(s).
