Okay Jeff, I thought of this, but it seemed wrong since I would be
importing the original file that contains the function which is calling
the function which is attempting to log (in the house that Jack built).
Let me be more clear. I have file A which contains most of the code for my
program and file B which only contains the new function. Code in file A
calls the function in file B which then calls the Logging function which
is in file A. I could just move the new function into file A eliminating
the whole problem, but I would rather learn the proper way to do this. I
think part of the problem is that this particular implementation does not
lend itself to OOP principles.
