Example

use good_lp::{variables, variable, coin_cbc, SolverModel, Solution};
let mut vars = variables!();
let a = vars.add(variable().max(1));
let b = vars.add(variable().max(4));
let objective = a + b;
let solution = vars.maximise(objective.clone()).using(coin_cbc).solve().unwrap();
assert_eq!(solution.eval(&objective), 5.);
