/** * 
 * This method creates and returns a new array that * contains all the colors stored in the original array, * except those colors that are equal to the target. For this * method, two colors are equal if they represent the * same color. * 
 * * 
 * Note that target may be null, and 'pixels' may contain * null elements. Two null elements will be considered equal. * 
 * * 
This is problem #5 for programming assignment #7.
