New "Get started"-Guide

[aeplay]

Goal:

• shows how to use create-jazz-app
• walks through the created structure, explaining fundamental Jazz concepts
  • schemas
  • provider setup (just pointing it out is enough)
  • reading from CoValues
  • editing CoValues
  • trying collaboration across devices/users
