  \class eZNavigationPart eznavigationpart.php
  \brief eZNavigationPart handles grouping of functions across modules
  \ingroup eZKernel

  A navigation part is a group of functions which belongs together. Every view can
  return the navigation part it should use. It is up to the view to return the
  proper navigation part. Views can internally check which navigation part to use,
  in the case of content/view the view will check the navigation part set in
  the section setup and use this.

  If the view does not return any navigation part it will default to the Content part.

  The navigation parts are controlled by the \c menu.ini file, look for the
  \c NavigationPart group.
  You can easily add new entries in override files or in extensions by adding
  to the \c Part list.
