/**
 * HDFView is the main class of this HDF visual tool.
 * It is used to layout the graphical components of the hdfview. The major GUI
 * components of the HDFView include Menubar, Toolbar, TreeView, ContentView,
 * and MessageArea.
 * 

 * The HDFView is designed in such a way that it does not have direct access to
 * the HDF library. All the HDF library access is done through HDF objects.
 * Therefore, the HDFView package depends on the object package but not the
 * library package. The source code of the view package (ncsa.hdf.view) should
 * be complied with the library package (ncsa.hdf.hdflib and ncsa.hdf.hdf5lib).
