/*  Image.h
 *
 *  CSE 326, Spring 2000
 *  Project 1
 *
 *  class image
 *  The main class for this application, containing all data defining a PGM
 *  image, and associated methods 
 *
 *  You are given:
 *
 *  - method readImage(...) which reads pixel data from PGM file.
 *  - operator [] which will allow you to reference pixels. e.g. if x is 
 *    an image object, x[0][0] is its first pixel.
 *  - some access methods
 *  - conversion method that takes labelled image object and scales pixel 
 *    values.
 *
 *  You need to write:
 *
 *  - constructor for image that takes title object as argument and
 *    dynamically allocates 2-dimensional array of correct size
 *  - method or methods to recursively identify connected components and
 *    label them as described in project description.
 *  - you may find it convenient to negate the input image before searching
 *    and labelling. Write a method for this.
 *  - method writeImage that creates appropriately-named output file from an 
 *    image object that has been labelled.
