Add date timestamp to log file for MC

[AndrewCunliffe]

The log looks good, the only helpful thing I think is missing could be a datestamp.

Something like f.write("Analysis completed on: {0}".scr datetime.now())

, but I'm not sure how you've used format.

Sure - good thinking - I'll add this in.

Added f.write("Analysis completed at: {0}".format(datetime.now()))

.format can be used to enter objects into strings the 0 corresponds to the order in the .format list for example try:

print("hello, my {0} is {1}".format('name', 'Andy'))

now fixed and merged
