Generate a QR Code as SVG

Demonstrates SVG output. An SVG is a vector image, so it stays sharp at any size, which suits print and responsive web pages. Setting output.format to svg and output.return to text returns the SVG document as a string in outputs[0].text. The SVG can also be written straight to a file with output.path, the same as a PNG.
