Hey Justin,
I think the decription is a bit misleading, specially this:
--Typically extname will be the name of a reascript or extension section
I just found anything you type there works (at least for these first tests i did) and i still fail to understand why this should typically be a script name or an extension.
Also this
-- Returns the size of the state for this extname.
The size in what units? Whats exactly a size of a state?
These concepts might be easy to grasp for somebody with some sort of programming experience but, as someone new getting into it, i cant help but struggle.
Thanks!!
