Class that "Navigation Center eXtended" file of OPF document
The Navigation Control file for XML applications (NCX) exposes the hierarchical structure of a Publication to allow the user to navigate through it. The NCX is similar to a table of contents in that it enables the reader to jump directly to any of the major structural elements of the document, i.e. part, chapter, or section, but it will often contain more elements of the document than the publisher chooses to include in the original print table of contents. It can be visualized as a collapsible tree familiar to PC users.
