Resume a long, looped simulation

Called from within a function, it stores/retrives the workspace of the latter, allowing resuming.

Tired of losing the progress in long, looped simulations (for instance, for scenario generation after and unexpected error or making CTRL-C), I wrote this small function to allow saving and later retrieving the values of the variables at the time of execution. In some sense, it is a sort of 'resume' capability. Placing the code in an inner loop, next time that a broken simulation is restarted, it will recover the data and keep with the recovered indices and variables. Unfortubatelly, the recovery process cannot update FOR loops.
