A typing game tutorial: (Traversy Media) https://www.youtube.com/watch?v=Yw-SYSG-028

Initialise application by typing index.html into the console.

Additions/changes implemented:

• Added colors to success/game over message
• Added 'typing' message to prevent surrounding items from bouncing around while user types
• Added difficulty Selector on ui (previously could only be manipulated via the js file)

Additional Thoughts:

• Refactoring with a css file would be neater, but the application is simple enough to warrant not using one.
