This is a command line calculator program, serving to demonstrate OOP and TDD concepts. Calculator forms token trees and evaluates them recursively.
Allowed operators are: '+', '-', '*' and '/'.
Order of operations and parenthesis work as expected.
Send 'd' to toggle debug mode, which shows the unwinding of token tree.
