/**
 * Demonstrates the morphing service of Instush.java, when turning an image into a greyscaled image.
 * The program recieves three command-line arguments: the name of a PPM file, and a number of morphing steps.
 * The source image (a string), and the number of morphing steps (an int, which determines how long will the mophing process take). 
 * For example:
 * java Editor3 ironman.ppm  300
 * creates a source image for "ironman.ppm", then creates a target image (the greyscaled version of the source image),
 * and does the morphing process within 300 steps.
