Learning shiny

This app is small but implements some big ideas I learned from Mastering Shiny, by Hadley Wickham:

• Packages (code).
• Shiny modules (code).
• Testing reactivity (code).
• UI as data (code).
• Server functions (code).
• Hierarchical select boxes (code).
• Plots (code).
• Themes (code).
