This directory holds the tablet interface component.

To Use:
1. Import the "events.sql" file into your MySQL database.
2. Modify the "web-app/connection.inc.php" file to have correct
   database-connection parameters for your MySQL instance.
3. Place the entire "web-app" directory in PHP-enabled, web-accessible
   space.


To Modify:
- To add new operations, modify the "index.php" file.
  I supplied three examples, which should get you started.
  See iUI documentation (iui-js.org) for examples of more widgets.
  The "event.php" file expects "screen" and "action" fields, with
  "p1" and "p2" and "p3" being optional for action-specific
  parameters. The "events.php" file has a "preprocess" function
  to do fancy things like the robot model + countdown timer.

- To add new parameters, don't forget to modify the table schema
  and the "fields" array in "events.php" in addition to usage in
  the "index.php" file.
