Cost function.

<t>Opensim currently is able to solve only tracking problem right (generate simulation that emulate existing experimental data) ? <br/> This is true ?<br/> It will be available in future a cost function optimization to do "what if" test ?<br/> (p.e. optimize for metabolic cost, maximum power...)<br/...
