* Added additional resource usage info for sim run. * Fixed so voluntary context switches output uses corresponding ru_nvcsw instead of ru_nivcsw due to copy and paste error. * Removed added resource usage data for page faults and block operations due to inconsistency on different OS. * Updated to have voluntary and involuntary usage data for both initilization and run for sim shutdown run summary.
