// To-do (priority: [H]igh, [M]edium, [L]ow):
// - [M] Move string literals
// - [M] correct public/private
// - [M] main context as default context
// - [H] Make it work! Understand "this", etc.
// - [H] what is the correct way of exporting the library?
// - [H] move scripts to github or similar
// - [H] do we need that the library is not cached? if so, how?
// - [H] See if ok that old versions are public
// - [M] Reorder functions
// - [H] Extend library to work on all the scripts
// - [M] Automatically handle case with only one list
// - [M] Add indication of URL to use to @require library itself
// - [M] correct @namespace and @homepageURL
// - [M] Auto-update
// - [L] Make public
//
// History:
// --------
// 2019.09.18 [0.1] First test version, private use only
