<p>A light singleton wrapper allowing to access permanent tasks.</p>
<p>When <strong>utils.delay</strong> is called, the task handler is used to create
the task. If <strong>utils.delay</strong> is called with <strong>persistent=True</strong>, the
task handler stores the new task and saves.</p>
<p>It’s easier to access these tasks (should it be necessary) using
<strong>evennia.scripts.taskhandler.TASK_HANDLER</strong>, which contains one
instance of this class, and use its <strong>add</strong> and <strong>remove</strong> methods.</p>
