urweb-color-thing-THING

The code in this repo is identical to the code in the other repo urweb-color-thing-T except:

• Here the "child" table is named thing - and in the other repository it is named t

The code in this repo doesn't compile.

The code in the other repo compiles and runs fine!

The compile errors for this repo are shown in in Issue 1.

Thanks for any help!
