## options ##
* h		 	 -> initial color hue
* s		 	 -> initial color saturation
* v  	 	 -> initial color value
* image		 -> the image to use for the background. Default is color-500.png
* centerX, centerY -> define a custom center position for the colorpicker. The center of the canvas is default
* drawInterval	   -> number of milliseconds between drawing. default is 10ms = 100hz. The real speed depends on the browser and computer.
* scale			 -> set the scale of the colorpicker. This is the number of pixels the arc for value is thick. When not set, it adapts to the canvas size: scale = min(w,h) / 10.

## functions ##
* onColorChange 	 -> callback on dragging the handles
* onCenterClick 	 -> callback on clicking on the center
to set options after creating the colorpicker use these functions.
* [name].setColorHSV(h,s,v)	->to set the color to a hsv value

to retrieve values at any moment use
* [name].getColorHSV() to get the color in HSV
* [name].getColorHSL() to get the color in HSL (for use in CSS colors)
