* - 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
