Trivial implementation of a responsive grid system using Flexbox and redux-responsive

	import { Flex, Box } from './flexbox.jsx';

	// A basic example. Note that the number of grid columns is not fixed,
	// instead you simply specify sizes as fractions (or decimals between
	// 0.0 and 1.0), and the items will be sized appropriately. For example,
	// the outer <Flex/> is full size at the `xs` breakpoint, 2/3 of full size
	// at the `md` breakpoint, and 1/2 at `lg` or higher.
	export const Basic (props) => (
	<Flex xs={1} md={2 / 3} lg={1 / 2} auto >
	<Box auto />
