Javafoil demo

Use javafoil to approximate flow over a 2D foil section. with effort, it can be used to approximate flow over a mast and sail section, by editing foil curves to become finitely thin.

the lift and drag coefficients can be used in lift and drag equations to calculate lift and drag forces. these coefficients are calculated with the assumption that the foil is spanwise infinite and equivalent, as well as unswept
