Describe the Issue

https://a2ui.org/guides/authoring-components/#2-implementing-the-component-client Should extend CatalogComponent
Also, it should use inherited props that are type safe.

https://a2ui.org/guides/authoring-components/#3-registering-with-the-renderer-client Bindings are now automatically bound by the @a2ui/angular framework adapter. The syntax to register components into a catalog is much simpler now.
