/*
Tools necessary for economic management
1. Current overall stats (!economy)
2. Statistical traffic trends in a graph 
	a. All time  / 1 year (whichever is smaller)
	b. 1 month
	c. 1 week
	d. 1 day
3. Freeleech analysis
	a. total download average during freeleech vs. normal conditions
	b. total stats of a freeleech - uploaded torrents, upload amount, download amount, snatches, etc.
4. Traffic trends over an account's life, on average
	a. at one week, one month, whatever (selectable range in weeks) - averages (up/down/ratio)
	b. given a selected timespan, average ratio (users who are 4-5 months old have X ratio)
	c. average date at which >50% of accounts with ratios >1 reach 1.0 and never dip below, stockpiling buffer
5. Raw numbers
	a. total torrents, seeders, leechers
	b. average seeds/leechs per torrent
	c. average snatches/user
	d. average seeding torrents/user
	e. users on ratio watch
6. Distribution graph of seedership vs. torrent percentage
	a. graph showing that the top 1% of torrents has 50% of seeders or whatever the numbers might be
7. Effects of economic changes
	a. number of users changed by ratio being changed
	b. project effects with intelligent mathematical analysis of a 24, 48 or 72 hour freeleech
