An "event list." This is a general-purpose type of script that lets you define the scripted events separately from the Script object.

The script is driven by a list of values; each value represents one step of the script. Each value can be a single-quoted string, in which case the string is simply displayed; a function pointer, in which case the function is invoked without arguments; another Script object, in which case the object's doScript() method is invoked; a property pointer, in which case the property of 'self' (the EventList object) is invoked with no arguments; or nil, in which case nothing happens.

This base type of event list runs through the list once, in order, and then simply stops doing anything once we pass the last event.
