Example

``` extern crate lyra2;

fn main() { let base1 = "abc".asbytes().tovec(); let base2 = base1.clone(); let lyra2result1 = lyra2::lyra2::lyra2(32, base1, base2, 1, 4, 4); println!("result: {:?}", lyra2result1); //result: [143, 99, 117, 139, 209, 120, 240, 20, 234, 63, 212, 223, 9, 255, 10, 97, 100, 109, 197, 116, 160, 182, 188, 242, 137, 14, 197, 41, 166, 167, 54, 12] } extern crate lyra2;
