"Start with a good name"

Starting to implement a story 1:
In order to save time on driving to pick up ordered items that are
already picked up,
As a deliverer,
I want to be able to see which orders are already picked up and which
are still waiting.

First thing we need to do is to wrap data from external systems with
domain abstractions. Thus, we specify that for orders made by customers.
"Start from the end"

This is one of the techniques described in the chapter on how to start
from a Statement.
I don't know yet what my code is gonna do, but in the end, I want an
order added to orders.
It should happen when user uses their front end

to invoke a remote method with two strings. Data sent across the network
in remote procedure calls is usually passed as series of either data raw
structures, or primitives, hence strings are used for user id and
content.
we need a userFrontEnd object

so let's create it! We assume that this class exists although it is not.
Thus, we are first specifying a need for such a class with a Statement,
and soon we will meet that need by creating this class.
