Number formatting

[ripienaar]

I often have to graph bytes or large numbers. It would be helpful if I could pass a function in that can be used to format the number shown, something like:

        memPlot := asciigraph.Plot(memUsed,
            asciigraph.Caption("Memory Storage"),
            asciigraph.FormatValue(func(v float64) string {
                        return humanize.IBytes(v)
            }),
            asciigraph.Width(width))

You'd call that when rendering the numbers

If you think this is a good idea I can try to contribute that, just wanted to sniff test the idea with you first @guptarohit
