This serves two purposes:  - To help in design level organization of procedural color palettes    (this eases the study of the class hierarchy)  - To provide a place to locate operations and methods, common to all    procedural color palette classes.Note that any procedural color palette is a normal color palette. Itsdifference is that some operations (most notably the selectNearestIndexToRgbmethod) are more rapidly calculated in some procedural defined palettes thatits normal method.*/public abstract class RGBProceduralColorPalette extends RGBColorPalette {    /// Check the general attribute description in superclass Entity.    public static final long serialVersionUID = 20061218L;    /// A procedural palette is "pure" if its contents are the original ones    /// defined by its filling procedure method "init", and are not pure    /// if they are modified in any other way.
