Create the component MessagePage 

  // ****     pages/messagepage.js    ****

import React from 'react'

export default React.createClass({
    displayName: 'MessagePage',
    render () {
        return (
            <div>
                <h2>{this.props.title}</h2>
                <p>{this.props.body}</p>
            </div>
        )
    }
})
