To run this example:

1. Make sure Appium 2 and the XCUITest driver are available
2. npm install in this directory
3. Update any of the capabilities that don't make sense for your system (iOS versions, etc...)

Now, in 5 different terminal windows opened up to this dir, run:

1. appium --config appium1.yml
2. appium --config appium2.yml
3. java -jar /path/to/selenium.jar node --config node1.toml
4. java -jar /path/to/selenium.jar node --config node2.toml
5. java -jar /path/to/selenium.jar hub

At this point, in another window, you can run node test.js to start 2 sessions simultaneously via the grid, and end them.
