// 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.
