Add newline after rendering

[schneems]

Currently when you execute this code:

require 'unicode_plot'
require 'stringio'

x = Array.new(100) { rand(10) } + Array.new(100) { rand(30) + 10 }
plot = UnicodePlot.histogram(x, title: "Histogram")
plot.render($stdout)

You will get this output:

Can we add an extra newline so that the label on the bottom of the graph isn't rendered on the same line as the next shell input?

OK. I'll make the modification to let render put a newline at the end of the output.

Thank you for your feedback!

Another solution is using IO#puts like below:

x = Array.new(100) { rand(10) } + Array.new(100) { rand(30) + 10 }
plot = UnicodePlot.histogram(x, title: "Histogram")
$stdout.puts(plot)

But, in this method the renderer cannot get real tty's property, so the result isn't colored. This restriction in using Plot#to_s is also a bug I want to fix.

Thank you for this fix and for this fantastic library!
