+/* Use print(message) for output.
+   Default tag for message is <pre>. Use print(message,'div') to change containing element tag.
+
+   Message can contain HTML markup. You may also tweak index.html and/or styles.css.
+   However, please, REFRAIN from improving visuals at least until your code is reviewed
+   so code reviewers might focus on a single file that is index.js.
