* Changes
* -------
* 31-Oct-2001 : Version 1 contributed by Serge V. Grachov (DG);
* 23-Nov-2001 : Overhauled auto tick unit code for all axes (DG);
* 12-Dec-2001 : Minor change due to grid lines bug fix (DG);
* 08-Jan-2002 : Added flag allowing the axis to be 'inverted'. That is, run from positive to
* negative. Added default values to constructors (DG);
* 16-Jan-2002 : Added an optional crosshair, based on the implementation by Jonathan Nash (DG);
* 25-Feb-2002 : Updated constructors for new autoRangeStickyZero flag (DG);
* 19-Apr-2002 : drawVerticalString(...) is now drawRotatedString(...) in RefineryUtilities (DG);
* 25-Jun-2002 : Removed redundant import (DG);
* 25-Jul-2002 : Changed order of parameters in ValueAxis constructor (DG);
* 06-Aug-2002 : Modified draw method to not draw axis label if label is empty String (RA);
* 05-Sep-2002 : Updated constructor for changes in the Axis class, and changed draw method to
* observe tickMarkPaint (DG);
* 22-Sep-2002 : Fixed errors reported by Checkstyle (DG);
* 08-Nov-2002 : Moved to new package com.jrefinery.chart.axis (DG);
* 20-Jan-2003 : Removed unnecessary constructors (DG);
* 26-Mar-2003 : Implemented Serializable (DG);
* 13-May-2003 : Merged HorizontalNumberAxis3D and VerticalNumberAxis3D (DG);
* 21-Aug-2003 : Updated draw(...) method signature (DG);
