/*
This script will generate TypeScript content for the code editor. It inlines 
the content of several files into one large string which can be passed to the
Monaco editor as an extraLib.

Important notes:

- Files must include the "Start Copy Here" comment indicated below. 

- This comment must be placed BELOW any import statements.

Run the script with `yarn scripts`.
