 * to the usual DefaultMutableTreeNode variables and methods, it has a boolean
 * for marking if the node has already been successfully expanded or not.  If
 * it has, it won't be regenerated when expanded again.  There's also a boolean
 * for marking if the node should be displayed in bold text or not.  This is
 * used to indicate whether or not a file node has calibration data.
