/r/tycoon simple velocity based market simulation

Quinn: kind of looks like a hamiltonian dynamics situation.

• Each commodity as supply, demand, current price, and price velocity
• Each purchase of the commodity by player or AI creates one point of demand
• Each sale of the commodity to the market creates one point of supply
• Every market cycle: if demand>supply then increase price velocity else decrease it

Velocity is typically 1.0 with a maximum and minimum determined by designer for desired volatility. Increments are typically 0.1 or -0.1.
