Mine Cetinkaya-Rundel d7391b19bc Convert examples to single file apps (#1685 )

* - Convert all example apps to single file app.R file
- Make relevant updates to Readmes to match up with app.R structure
- Add color to plots (RStudio blue)
- In 04_mpg example: Show outliers by default, as opposed to hide, since this is more routine
- In 06_tabsets and 08_html examples: Don't name random data vector "data"
- Add extensive comments to app.R files and use consistent formatting of comments across examples
- In 09_upload example: Use req() to check for NULL entry

* add news entry summarizing changes

* use true RStudio blue, #75AADB

* Conver shinyApp calls at the end to drop argument name in examples 3-11, except for the custom HTML example. Kept them in for examples 1&2 for completeness in first exporuse to function.

* Pull news items that got added before this PR was merged

* Update comment for shinyApp function -- it creates an app object, doesn't run the app

Readme.md

This example demonstrates the following concepts:

Global variables: The mpgData variable is declared outside of the ui and server function definitions. This makes it available anywhere inside app.R. The code in app.R outside of ui and server function definitions is only run once when the app starts up, so it can't contain user input.
Reactive expressions: formulaText is a reactive expression. Note how it re-evaluates when the Variable field is changed, but not when the Show Outliers box is unchecked.
