Example User Interface Definition
In this section we will use an Epic and an Application to completely describe the familiar e-commerce process of filling an online shopping and checking out. This involves just enough complexity to show the UI design in RIDDL without overburdening the reader with domain complexity.
The application provides the inputs and outputs that a user can use to communicate with the system it represents.
The epic describes what happens in certain use cases of the application.
TBD: Finish defining the example, with pictures
