Vending Machine

A simple C# command line program demonstrating OOP.

Class: Menu (provided)

Class: VendingMachine (the controller)

1. Handles the Display class (which calls the Menu Class)
2. Gets the stuff from the inventory file
3. Creates the VendingItems Objects (adds them to a list)
4. Updates the VendingItems Objects' inventory when something is vended

Basically it uses all of the other classes...
