----Druid Rich Text Custom Component.
--- <b># Overview #</b>
---
--- 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.
---
--- Create Rich Text on your GUI Text Node. All properties of the text node will be used as default for the text.
---
--- <b># Notes #</b>
---
--- • Nested tags are supported
