Cheap OO system description

[Enrico Colombini <erix@...>]

For those not interested in my wxLua example (gpeddler 2) but only in a simple 
approach to objet-orientedness in Lua, here is a description of my system:

It doesn't use metamethods but only 'basic' Lua, so it should be easier to 
digest for programmers used to procedural languages. On the other hand, it is 
rather inefficient when large numbers of small objects are involved.
