Needs to be implemented by everything that wants to be a LineSearchCondition

Required methods

fn eval(
    &self,
    cur_cost: F,
    cur_grad: T,
    init_cost: F,
    init_grad: T,
    search_direction: T,
    alpha: F
) -> bool

Evaluate the condition

fn requires_cur_grad(&self) -> bool

Indicates whether this condition requires the computation of the gradient at the new point
