Simple WebApp wrapper for MJML to be used by non-tech users.
Why?
Even though MJML has a node package to render templates, we can't use all of its features in a web environment, since it was made for Node, not browser. Therefore, non-tech users would have to install and learn a lot of things not needed for them to be able to create simple templates. So... Aiming for a fast solution, I created this simple wrapper that works for most of the MJML default components, including one of the most needed for my case: mj-include.
