Detailed Description

ColorUnit class. An instance of ColorUnit can represent a value for the red, green, blue and alpha component of the class ColorRGBA. Furthermore this class is used for the value and saturation component of the class ColorHSV. The class handles the many possible variations a color value can be set (e.g. integer, float, string values can be given as parameter). The integer values are of range 0-255, the float values are of range 0-1.0 and the strings given are in hex format "00"-"FF". ColorUnit provides certain conversion functions as well, that will convert its value to the needed type. This class is used by the class ColorRGBA and ColorHSV.
