## An example

```fn main() {
use slp::*;
use slp::Rational64;
use slp::Solution;
let input = "
vars x1>=0, x2>=0
max 2x1+3x2
subject to
2x1 +  x2 <= 18,
6x1 + 5x2 <= 60,
2x1 + 5x2 <= 40
";
let mut solver = Solver::<Rational64>::new(&input);
let solution = solver.solve();
assert_eq!(solution, Solution::Optimal(Rational64::from_integer(28), vec![
Rational64::from_integer(5),
Rational64::from_integer(6)
]));
match solution {
Solution::Infeasible => println!("INFEASIBLE"),
Solution::Unbounded => println!("UNBOUNDED"),
Solution::Optimal(obj, model) => {
println!("OPTIMAL {}", obj);
print!("SOLUTION");
for v in model {
print!(" {}", v);
}
println!();
}
}
}```
