[aktanoff]

The README says that rce snippet and others that based on Component, automaticly imports { Component }

import React, { Component } from 'react';

but actually it doesn't

<content><![CDATA[import React from 'react'

There was a bug in version 1.0.0, it now correctly imports Component from React.Component.
