Allow the Address object to have varying degrees of information to allow general store searches. A full address should still be required for the order, though.

The documentation is pretty lacking at this point. Document all of the classes and functions, as well as the standard installation, usage, contributing, etc. sections.

Add `add_coupon` and `remove_coupon` methods to the Order object.

Add a Tracker object that can be passed callbacks for order updates.

Add an example of how to continuously track orders.

The Menu categorization that was taken from the `pizzapi` module were done well, however the product codes that were displayed are actually codes that describe categories, not codes that can...

The current menu searching method is silly. Add a keyword search.
