<h1>Module <code>RichText</code></h1>
<p>Druid Rich Text Custom Component.</p>
<p>
<b># Overview #</b>
<p> This custom component is inspired by <a href="https://github.com/britzl/defold-richtext" target="_blank">defold-richtext</a> by britzl.
It uses a similar syntax for tags but currently supports fewer tags.
<p> Create Rich Text on your GUI Text Node. All properties of the text node will be used as default for the text.
<p> <b># Notes #</b>
<p> • Nested tags are supported
