Justify columns

[adam-cyclones]

For future searches, and this is also a bit of a feature request too.
I think it could be fairly trivial to patch something like this as a boolean, {justify:true}, the harder bit is using the process.stdout.on('resize') event to make this responsive.

Thanks for this amazing tool!

//add this to your constructor settings and your columns will justify base on your headings.
get colWidths(){
    let len = (process.stdout.columns / this.head.length);
    return this.head.map(heading => Math.floor(len))  
}
