    <p>You can use /sandbox/ for writing and testing your own code. Nothing in /sandbox/ will get checked into the repo, except files that end in .example (so don't edit or add those files). To get started run `npm start` and open the index.html</p>
    <pre>npm start</pre>

      In developer console, Sources tab, look for <code>clearCacheForPlayer</code> function.
      Place a logpoint at function closing. Logpoint content should be:
    </p>
    <pre style="font-size: 1.2em;">'middlewareInstances nr', Object.keys(middlewareInstances).length</pre>
    <p>
      When one or more players are removed, the number of instances should *NOT* grow.
