Add a module with examples

Since we got a strange error with this repos as a dependency, I propose to create a separate example project where this plugin will be included as a dependency. It means we can build this small project in CI to check if the plugin is broken and it can not be used as a dependency.
On the other hand, we can use this example project as a great example for other users who want to use this plugin in their plugins.

I am open for discussion
