[PySimpleGUI] Tutorial - Name, Address, Phone GUI

[PySimpleGUI]

Following up on the Focus suggestion. Perhaps I should explain how I'm setting focus today.

Focus is set when the first one of these items is found:

• Button that closes the window - like Submit, OK
  
• Single line text input
  
• Multi line text input
  

That seemed like a reasonable algorithm for now. I wanted to focus, but to expose a way to modify in the first version.
