elegant to terminate optimization and proceed as if
optimization had converged.  (To genuinely terminate the run during
optimization press Control-C twice.) This is very useful if one wants
to get a look at the partially optimized result.  If one uses parameter
saving (run_setup) or save_lattice one can make a new
run that starts from the optimized result.

summarize_setup -- A flag indicating, if set, that a
summary of the optimization parameters should be printed.
