-#= Model of a kite-power system in implicit form: residual = f(y, yd)
-
-This model implements a 3D mass-spring system with reel-out. It uses six tether segments (the number can be
-configured in the file data/settings.yaml). The kite is modelled using 4 point masses and 2n aerodynamic 
-surfaces. The spring constant and the damping decrease with the segment length. The aerodynamic kite forces
-are acting on the inertial kite point. 
-
-Four point kite model, included from KiteModels.jl.
