Trait Func 

pub trait Func<U>: Fn(&[f64], &mut U) -> f64 { }

A trait representing objective and constraints functions.

An objective function takes the form of a closure f(x: &[f64], user_data: &mut U) -> f64

• x - n-dimensional array
• user_data - user defined data for objective and constraint functions
