HELP

When a Help button is pressed in any VolVis window, this Help window will be
used to display the appropriate help.  The scroll bar on the right side of 
the window can be used to scroll through the text.  If a word or phrase is
underlined, more help exists on this subject.  To see this help, highlight the
underlined text, and press the More Help button.  The text can be highlighted
by placing the mouse over an underlined word and clicking the left 
mouse button. If no text is highlighted, an error message will be generated.
