/*
	This test file puts the SegmentRouter to the test by running a million lookups on a handful
	of routes. The routes are read from two files, blog.txt and github.txt, and added to two separate
	routers. The lookups are then run in two separate loops, one for each router.
	Each lookup is timed and the memory usage is also printed out at regular intervals.
	The requests are randomly picked from the array of routes.
