LevenbergMarquardt2DMaxFunctionEval Property

Maximum number of function evaluations. Default 200

This may not be hit exactly, since one iteration can trigger several function evaluations.

In case a Jacobian is not provided, this can be set app.

since the number of evaluations per iteration is 1 per default and then 2 evaluations per 1/JacobianRecalc iterations
