Executes all child activities simultaneously and asynchronously. A Parallel activity operates by simultaneously scheduling each Activity in its Branches collection at the start. It completes when all of its Branches complete or when its Completion Condition property evaluates to true. While all the Activity objects run asynchronously, they do not execute on separate threads, so each successive activity only executes when the previously scheduled activity completes or goes idle. If none of the child activities of this activity go idle, this activity execute in the same way that a Sequence activity does.
Most of the properties on this activity can be set using an expression. That is why when we set a string value, we must put that string value under "".

In this example, we start 3 browser windows, navigate to google, type "test" followed by an enter key and when all the browser windows complete their search, we display Done.
