+- implement a path following controller (not in this package, but in SimpleKiteControllers.jl)
+- implement a function that runs the controller for at least one figure of eight (and some initialization to reach a stable, repetitive trajectory) and that returns the average traction force in x direction and the average steering power
+- add an optimizer using Nomad.jl that optimizes the 7 parameters
