How to use an SVG file in a SvgIcon in Material-UI
<p>I've got an SVG file and I want to make an SvgIcon component out of it, how should I do that?</p>

<p>In the <a href="http://www.material-ui.com/#/components/svg-icon" rel="noreferrer">documentation</a>, all the examples use either predefined Material Icons or a strange notation of <code>&lt;path d="M10 20v-6h4v6h5v-8h3L12 3 2 12h3v8z" /&gt;</code> which I have no idea what it is!</p>
