Example list file

[ellthompson]

This PR reintroduces the examples.js file to the examples browser. This file is now automatically generated as part of the examples-directory.js script with the same format as before:

/* eslint-disable no-unused-vars */
var categories = [
       {
            "name":  "<category>",
            "examples": [
                   "<example>"
            ]
       }
];

This file is generated in the dist folder.
