Brail chart's complementation should be better.

MemMeter is ugly. Sequence such as [0, 3, 3] should be complemented in better way.

    // watch if 0-3 line is well complemented
    let d0: Vec<u32> = vec![0, 3, 0, 0, 0, 3, 0, 0];
    let d0: Vec<f64> = d0.into_iter().map(|d| d as f64).collect();
    let height = 4;
    let brail = b32::get_brails_complement(height, 0.0, 20.0, d0);
    show_brail(brail, height);

In addition, [0, 3, 3, 3] looks below:

0 to 3 line overruns.

    // watch if 0-3 line doesn't overrun
    let d0: Vec<u32> = vec![0, 3, 3, 3];
    let d0: Vec<f64> = d0.into_iter().map(|d| d as f64).collect();
    let height = 4;
    let brail = b32::get_brails_complement(height, 0.0, 4.0, d0);
    show_brail(brail, height);
