Demand formula

[Unknown98]

While going through the demand code I noticed a bug that I had missed when initially creating the formula. When calculating average ticket prices on a particular route, the game took into account ALL the flight history. So if an airline had flown that route a month ago, but not since, those prices would still affect the average price, and thus your demand. I've changed it now to only take the average of the past 7 days. That way it is an average of the airlines that are currently flying the route rather than a complete average of the entire history of the route.
