The UI has two tabs Vending Machine and History
In Vending Machine you can insert a quarter, remove a quarter,
and push for soda. The UI shows how many sodas are left and the state of
the vending machine.
In History you can see a list of soda purchase history.
The backend implements a simple state machine to manage the state of the vending machine.
