This script allows you to set certain event pages as "parallel pages".
Other event pages can be assigned "parallel pages", which allows you to execute the commands on the parallel page concurrently.
This is similar to setting a custom move route for your page, except now you have full control over how it should behave.
The parallel page obeys all event conditions, so if the page conditions for the parallel page are not met, then it will not run. You can have pages running while their parallel pages are not running.
Currently, any event page may have at most one parallel page. However, you may define multiple parallel pages in a single event.
