Improve logging to add timings and continue after failure

[matthewharris02]

Improve the logging capabilities to:

• have the clock time of completion of processes (allowing cross-checking with computer load)
• ensure logging of final time works even if error (e.g., implement a try-except statement)

Potentially:

• add RAM profiling
