Thanks Ben, I see how those are less optimal, I was hoping for something
along the lines of context->global()->GetFunctionTemplate("constructor"),
or something along those lines.
The only problem I have with my approach is that I need a Finalize function
on each wrapped class that pretty much just resets the permanent handles.
Thanks Again!
