   Hints for operating the GUI:
 
   *) Use the [Show] button to see a projection of the currently selected
      set of tags.
 
   *) You need to "connect" the table (switching on the small radiobutton)
      to command the GUI to show the particles transformed along the GUI
      parameters.
 
   *) You have to provide a valid table to browse the data.  A valid table
      should index only particles in the data set (although not necesssarily all of them)
      If none is available, just generate one using the GUI (Table>generate blank)
 
   *) Clicking on individual particles in the generated scene will allow
      you to access the table values attached to the particular particle
      and/or retrieving the particle directly form disk
