	# TO DO:
	# Save diagnostic values (section commented out below) to an output csv?
	# Which values to save?
	# Write diagnostic values to same log.csv as model params. Append to existing
	# file so that multiple model runs can be recorded and compared.
	# ...

Model diagnostics could be output to standalone file(s) in the model output folder, or they could be saved in the log file (issue #6), along with the model input params - may make it easier to compare different model runs?
