/** Simple actor tag parser. If the tag is parental, {@link Group} is created instead of {@code Actor} to handle
 * children tags and plain text. This widget is advised to be used only as a child when, for example, a cell in a table
 * needs to be filled with a mock-up actor. Text between tags is added to the group as a label. Mapped to "actor",
 * "group".
