Judson's response would have been correct if the say method in hello 
would have called a core method from the instance of core object that 
create the hello object...

I think Jesus' response is what I needed, I have not tested it yet... 
but I am excited to try this on Monday!!! However, Now how would this 
work if both classes are in different files???  I think this is what I 
need if they were in same file, so can I just require the Hello file at 
the top of core, no module stuff needed if want them in separate 
files?!?!

Thanks again Jesus
Matt
