Almost there!!

(Thanks to you and Jeff Emanuel for all your help).

I have thinks WORKING! but only if I use Jeff's trick of:
interp.set("ListBO", this.getClass()).  If I try to
"import quovix" or "from quovix.business.util import ListBO" from
Python after setting the classloader per your instructions, Python
gives an "ImportError: no module named quovix".  Oddly, it can import
things like java.util.Date.  I'm unsure why it can't find my own
classes -- obviously the MultiClassLoader can because all this stuff
is being called from ListBO itself.  So it's a bit strange.  But I can
work around that certainly.

Also I'm curious why this works:

interp.exec("import ListBOFoo");
Class pclass = (Class) interp.eval("ListBOFoo.ListBOFoo").__tojava__(Class.class);

But this doesn't:

interp.exec("mod = __import__('ListBOFoo')");
Class pclass = (Class) interp.eval("mod.ListBOFoo").__tojava__(Class.class);

The second dies on the eval claiming that there is no such symbol in
Python.  Not a biggie but a weird thing anyway.

Thanks for all your help!
