Q:
Change Program Flow based on Available Libraries
I am developing a Python model that will support graphing if the correct modules are installed. I would like the source code to be the same if possible, IE, if the graphing model can't load, graphing would be ignored from the menu logic.

Q:
Instantiating a unique object every time when using object composition?
As an example, just a couple of dummy objects that will be used together. FWIW this is using Python 2.7.2.

self.tool = tool
