API Evolution Kata

Today's Kata will evolve a simple API from both the server and the client point of view. The end goal is to produce an API for crafting delicious, delicious burritos.

You will need a pair for this. One person will be writing the server and one person will be writing the client. This will let us evolve our API quickly and require both people to make the appropriate changes. Luckily, Hyper can play both roles!

For my ((a family member))'s ((an event)) present about ((a number)) years ago,
I got him a ((gift:a noun)).   Not a ((an adjective)) ((gift)) or a loud one or
even a ((an adjective)) ((gift)) that runs around chasing its ((a body part))
and drooling on the ((a noun)).  I got them a ((a proper noun)), bred in China
thousands of years ago to be the ((a plural noun)) of the royal family.  We
named it ((a proper name)).
