[Laszlo-dev] Simple idea on how to update dynamic instantiation of user classes

[P T Withington]

Right.  I sent the same caveat to Don.  His final script will be  
driven off the defined classes.

Even so, the script will not be able to find all the cases that need  
updating because it is only going to do trivial analysis, looking for  
tag names as arguments to `new` and `instanceof` and replacing them  
with class names.

I am working on some better compile-time warnings.

You will always get a runtime warning in debug mode because you will  
be calling `new` or `instanceof` on undefined.
