/**
 * The main class for the NimROD Look&Feel.
 *
 * To use this Look&Feel, simply include these two lines into your code:<br>
 * <code>
 * NimRODLookAndFeel NimRODLF = new NimRODLookAndFeel();
 * UIManager.setLookAndFeel( NimRODLF);
 * </code>
 * You can change the default theme color in two ways.
 * 
 * You can create theme and change de colours with this lines:<br>
 *   <code>
 *   NimRODLookAndFeel NimRODLF = new NimRODLookAndFeel();
 *   NimRODTheme nt = new NimRODTheme();
 *   nt.setX( Color);
 *   ....
 *   nt.setX( Color);
 *   NimRODLF.setCurrentTheme( nt);
 *   UIManager.setLookAndFeel( NimRODLF);
 *   <code><br>
 * This way is good if you can change the sources and you want the program works *only* with NimRODLF. 
 *
 * If you don't have the sources you can change the theme color including same properties in your command line and the look and feel
 * will do its best... This couldn't work if the application changes the system properties, but, well, if you don't have the sources...<br>
 * For example:<br>
 *   <code>java -Dnimrodlf.selection=0x00cc00 XXX.YOUR.APP.XXX</code> will colour with green the selected widgets<br>
 *   <code>java java -Dnimrodlf.s1=0xdde8ee -Dnimrodlf.s2=0xb7daec -Dnimrodlf.s3=0x74bfe6 XXX.YOUR.APP.XXX</code> will colour with blue the background of the widgets<br>
 * The values are in the tipical HTML format (0xRRGGBB) with the red, green and blue values encoded in hexadecimal format.<br> 
 * These are the admited properties:
 * <ul>   
 * <li>nimrodlf.selection: this is the selection color</li>
 * <li>nimrodlf.background: this is the background color</li>
 * <li>nimrodlf.p1: this is the primary1 color (緿on't you understand? Patience?</li>
 * <li>nimrodlf.p2: this is the primary2 color</li>
 * <li>nimrodlf.p3: this is the primary3 color</li>
 * <li>nimrodlf.s1: this is the secondary1 color</li>
 * <li>nimrodlf.s2: this is the secondary2 color</li>
 * <li>nimrodlf.s3: this is the secondary3 color</li>
 * <li>nimrodlf.b: this is the black color</li>
 * <li>nimrodlf.w: this is the white color</li>
 * <li>nimrodlf.menuOpacity: this is the menu opacity</li>
 * <li>nimrodlf.frameOpacity: this is the frame opacity</li>
 * </ul>
 * 縋rimary color? 縎econdary? 縒hat the...? Cool. <a href='http://java.sun.com/products/jlf/ed1/dg/higg.htm#62001'>Here</a> you can learn what 
 * i'm talking about. Swing applications have only 8 colors, named PrimaryX, SecondaryX, White and Black, and <a href='http://java.sun.com/products/jlf/ed1/dg/higg.htm#62001'>here</a>
 * you hava a table with the who-is-who.<br>
 * You don't need to write all the values, you only must write those values you want to change. There are two shorthand properties, selection and background.
 * If you write nimrodlf.selection or nimrodlf.background the NimRODLF will calculate the colors around (darker and lighter) your choose.<br>
 * If nimrodlf.selection is writen, pX, sX, b and w are ignored. 
 * Ahh!! One more thing. 0xRRGGBB is equal #RRGGBB.
