===== Lab #3 The Matrix Class =====

The main purpose of this lab exercise is to use the Java constructs we have been studying:

  * Arrays
  * Control flow statements (conditionals and loops)
  * Class and method creation
  * Text output

We will accomplish this goal by writing an application that can add and subtract two like
matrices. A Matrix is simply a 2 dimensional array, or an array of arrays.

A few thoughts on the lab...
  - This is another long lab and some lecture material has to be reviewed together
  - I expect that I will allow time from Thursday's lecture to complete the lab.
  - It helps to think of an array as a row of elements and a 2D array as having multiple rows.
  - for a type such as int[][], think of int[number-of-rows][number-of-columns]
  - My recommendation is to use nested for loops to traverse the elements of the matrix.
    - the first, or outer-most for loop will iterate the rows
    - the second, or inner-most for loop will iterate the columns (or, if you prefer, a single array)
    - remember to start counting with element 0.
