parsePreprints

Had a 'links' error when attempting to download all (more than one I think) around the 102nd paper starting from a default range of 2017-01-01.

I just put this in to bypass so far

	# The Relationships data has links to more information
	# Use our helper function to extract those links and put them in our preprint object
	try:
		preprint.parseRelData( rel )
	except Exception as prd:
		print(prd)
		print("error: on preprint ", len(preprints)+1, prd)
		return

so could do a pull request along those lines, I haven't made an error log yet to record which entry

@bluetyson thanks for the testing/debugging. This is very helpful!

I believe this is due to the COS API simply returning all preprint links in the database and not checking the "status" field. You're likely getting links to withdrawn preprints, which no longer have links.

Thanks, thought it might be something like that, so just skipping them for the time being.
