//  On my honor:

//  - I have not used source code obtained from another student, 
//    or any other unauthorized source, either modified or unmodified.  
//	
//  - All source code and documentation used in my program 
//    is either my original work, or was derived by me from the source
//    code published in the textbook for this course.
//	
//  - I have not discussed coding details about this project with anyone
//    other than my instructor, ACM/UPE tutors or the GTAs assigned to this
//    course. I understand that I may discuss the concepts of this program
//    with other students, and that another student may help me debug my
//    program so long as neither of us writes anything during the discussion
//    or modifies any computer file during the discussion.  I have violated
//    neither the spirit nor letter of this restriction.
