While working on JDK-8309748 it became clear that both the code that generates the checkbox-based user interface in the API summary pages and the user interface itself could be improved.

On the Java side, the code to generate the interface is currently mostly located in the SummaryListWriter subclasses. This code should probably be used to the Table class or get its own class.

On the user interface side, it is currently necessary to click each checkbox individually to select all or none of the checkboxes. There should be an additional checkbox labelled "All" to select or deselect all checkboxes.
