Wicket is a Java web application framework that takes simplicity,
separation of concerns and ease of development to a whole new level.
Wicket pages can be mocked up, previewed and later revised using
standard WYSIWYG HTML design tools. Dynamic content processing and
form handling is all handled in Java code using a first-class
component model backed by POJO data beans that can easily be
persisted using your favorite technology.
The newest version!

* Used to unify all metadata methods across the various objects.

* This allows for metadata to be mutated at arms length without dealing with the intricacies of
* each type that implements it.
*
* Due to the inability to refer to implementing types (e.g. Self in Rust) we use the {@code R} parameter
* to return the type of the implementing object.

* @param
* The base type the metadata object must extend. (e.g. {@link java.io.Serializable})
* @param
