Event broadcast and receive nodes for Node-RED.

<p>
    Event-driven notifications. Create an event from an input msg.topic.
    An instance of this node will receive the same msg as that sent with a matching <code>msg.topic</code> to any <code>event-out</code> node.
</p>

<h3>Inputs</h3>
<p>
    There are no inputs. The node is triggered by a <code>event-out</code> node with a matching input <code>msg.topic</code>
</p>

<h3>Outputs</h3>
<p>
    The node outputs the node that was input to the matching <code>event-out</code> node.
</p>

<h3>Node Settings</h3>
<dl class="message-properties">
    <dt>Name <span class="property-type">string</span></dt>
    <dd>A short description shown in the admin interface</dd>

    <dt>Topic <span class="property-type">string</span></dt>
    <dd>
        <p>
            <b>REQUIRED</b>. The topic name to match.<br>
            The defined topic string may include the character <code>*</code> (or <code>+</code>) to act as a single-level wildcard.
            Use <code>**</code> or <code>#</code> for a multi-level wildcard.
            The <code>/</code> character acts as a level (namespace) separator for the wildcards.
        </p>
        <h5>Example</h5>
        <p>
            <code>one/*/three</code> will match input topics of <code>one/two/three</code>, <code>one/99/three</code>, etc.<br>
            <code>one/**</code> or <code>one/#</code> will match input topics like <code>one/two/three</code>, or <code>one/99</code>.<br>
        </p>
