 // A HyperlinkButtonCell is used to create an NSButton that looks and acts
 // like a hyperlink. The default styling is to look like blue, underlined text
 // and to have the pointingHand cursor on mouse over.
 //
 // To use in Interface Builder:
 //  1. Drag out an NSButton.
 //  2. Double click on the button so you have the cell component selected.
 //  3. In the Identity panel of the inspector, set the custom class to this.
 //  4. In the Attributes panel, change the Bezel to Square.
 //  5. In the Size panel, set the Height to 16.
