title: customize material-ui List width
body: <p>Is there any way to customize material-ui List width? It looks like no matter what width I put in <code>style</code> or <code>innerDivStyle</code>, it's always maxed out at <code>350px</code>. I'd love to see a way to set custom width (like <code>100%</code> or whatever arbitrary width) to List. BTW, currently I'm using material-ui <code>v0.15.0-beta.1</code></p>
