extends FourDimensionalColor

Class representing colors in the (cyan,magenta,yellow,black) space.

Internally all colors are represented as (cyan,magenta,yellow,black) in [0,1]x[0,1]x[0,1]x[0,1].

1	CmykColor(cyan=NULL, magenta=NULL, yellow=NULL, black=NULL, maxColorValue=1)

`cyan`	A `vector` of `numeric`, or a `Color` object. If a `vector` of `numeric` it specifies the amount of cyan in the range [0,`maxColorValue`]. If a `Color` object, the colors according to `getColors()` on that object will be used.
`magenta`	A `vector` that specifies the amount of magenta in the range [0,`maxColorValue`].
`yellow`	A `vector` that specifies the amount of yellow in the range [0,`maxColorValue`].
`black`	A `vector` that specifies the amount of black in the range [0,`maxColorValue`].
`maxColorValue`	A `numeric` value specifying the maximum value the values in the different channels can take.

Moreover, the number of colors will be the same as the length of the longest vector of the above. If some of the other vectors are shorter, their values will be looped over to get equal lengths.

Methods:

	`asRgbColor`	-
	`getColors`	-
	`maximizeBlack`	Maximizes the black channel to 'save' the other colors.
	`plotParallel`	-
	`setChannel`	Sets the color values in the specific channel.
