I have a class called GUI which draws my GUI.  I then have another class 
called Calc which does all the calculations.

One of the GUI objects I'm using is a progressMeter (pmw) 

The progressMeter is declared in GUI and it has an update function called 
updateProgress.  So you can have a loop and keep calling updateProgress 
and increment your progress.
This works fine and dandy if I call updateProgress in the GUI class.  The 
problem is I can't monitor the progress in the GUI class because the 
calculation is being done in the Calc class.

Ideally, I want to called updateProgress in the loop of Calc Class.

I thought for a second since python passes stuff by reference I could just 
pass a reference to the progressMeter to Calc and then do the update there 
but that doesn't work.

Do I need to make the progressMeter global?  I read that's not very 
elegant.

How would I go about letting the Calc class update progressMeter.  Thank 
you for your help.

~Ed
