Title: Re: Exposing class instances as globals

Woops, spoke too soon.  Solved!  All I needed was a setglobal call in the right place.

Looking through the archives, I've seen several people looking for tips on how to expose classes to Lua.  I've attached an example bit of code I created while learning the Lua API that might be of help to others.

The code shows how to expose a class as creatable (and garbage collectable) from Lua, and how to expose an instance of an already instanciated class.  Be forewarned, this code was written in one pass and doesn't follow any real design pattern.
