Due: Friday, June 16 at midnight

Late penalties: 20 points per partial day late.  That is, programs
	turned in after midnight Friday and before midnight Saturday
	will have 20 points deducted for late, programs turned in after
	midnight Saturday and before midnight Sunday will have a total
	of 40 points deducted for late, etc.  Since this assignment 
	uses the Drawing Window, you should give considerable attention
	to getting the assignment in early if you cannot use the
	Drawing Window from a remote location.

Total point value of assignment:  100 points

Late submissions not accepted after: Monday, June 12 at midnight

This assignment is to be done INDIVIDUALLY.



Create a directory, A6, which will contain all parts of this assignment.
(In this assignment the directory A6 will contain a file
named Asg6.java.)  

Assignment:

	Problem 3.10 (page 48).  Finish the two-dimensional Vector-like
	structure Matrix.  Each element of the Matrix is indexed by two
	integers that identify the row and column containing the value.
	Your class should support a constructor; methods addRow and
	addColumn that append a row or column; the elementAt and
	setElementAt methods; and width and height methods.  In 
	addition, you should be able to removeRowAt and removeColAt.
	(Note:  the method name is removeColAt, not removeColumnAt.)

	Two additional methods are needed:

	public boolean equals ( Matrix other )
	// post:  returns true if this contains identical information 
	//        to other;  otherwise, returns false.

	public String toString()
	// post:  returns a String representation of the Matrix.
	//        representation may contain newline characters (\n).


Input:  

	Input should be contained in your test program (main).
	Use the ReadStream class (page 334) that is part of Bailey's
	structure package for both input and output.

Output:

	Print your name, the assignment number, and a short description
	of the assignment.  Use the System.out commands.

	Output should be contained in your test program (main).
	Your class will also be tested with other test program(s).

Other requirements:

	Follow the style standards to be found on your instructor's
	web page for CPSC 210.

	Submit your program using the handin command.  There is a link to
	the handin description on your lab page (www.cs.clemson.edu/~lab210).
