Add fruit shipping example

[KyleAMathews]

Main odd thing was the typescript error here — the code runs as expected though:

Also I was trying to log out the materialized view after each step but... not really sure how to do that.

Fixed up and added comments. TS error was a misunderstanding.

Neat! Feel free to merge or close as you'd like. I'm not sure it adds much over the other examples.
