		# Why lu_nick and lu_address?
		#
		# One of the biggest slow-downs for a log analysis program is
		# nickname tracking. In a previous version of silan, this was
		# done very cleanly by massaging a single list of users until
		# the right user or group of users could be found. This proved
		# to take an enormous amount of effort, and was unacceptable.
		#
		# From this came the UserCrate. The purpose of this is to do
		# pretty much the same thing as a big list would. The
		# difference is in these two dictionaries. Rather than repeated
		# iterations through a list of users, a user can be quickly
		# obtained simply by looking it up by whatever information is
		# on hand.
		#
		# There is a cost of memory usage involved, but the gain in
		# efficiency and understandability is enormous.
