Changes for Parallel Version Only

Changes to the parallel version are made by Y. Wang (ANL), unless otherwise noted.

• In the last version, we added the ability to change the randomization mode for different processors. However, the default mode was not changed to one of the improved methods, even though the documentation said it had been changed. The default mode has now been changed mode 3 (see the documentation for global_settings).
• Updated to get the correct latest result from genetic optimization by using the right population group. Improved population log file for multiple restarts.
