Homework assignment one:

An external file contains numbers which represent an nxn matrix of 
values. For example:

1 2 3 4
5 4 3 2
3 4 5 6
7 6 5 4

is a 4x4 matrix. We wish to find the determinant of any nxn matrix using
the classical recursive definition of determinant. 

We also wish to organize our work using proper abstractions and classes
in C++. In this regard, we shall create a matrix class with appropriate
functionality, and use this as the basis for our solution to the problem
of calculating the determinant. See class notes for the definition of
determinant and for the appropriate functionality to be included in the 
matrix class.

When demonstrating your solution to this (and all problems in this class)
you must use the make utility and an appropriate makefile. Your work must
be divided appropriately into several source files and header files. 

Work must be tar'd and gzipped and presented to your instructor in this 
form. Your work must be warning and error free and must work on my data.
Make sure you check all marginal and exceptional cases.
