What's Changed Here?

We've done a couple of things for this part:

• Created a <Menu> component
• Created a <Footer> component and added the menu to it
• Edited the <Header> component to add the menu to it
• Edited the <Layout> component to reflect these changes
• Added support for SASS - just in case you like it!

To install sass, run npm install --save node-sass gatsby-plugin-sass. Then add it to your gatsby-config.js file as a plugin.
