Detailed Description
The Matrix class provides the matrix abstraction. A matrix of order numRows X numCols is an ordered 2d array of numbers arranged in numRows rows and numCols columns. For example, a matrix 
of order 2 X 3: 
A = \left[ \begin{array}{ccc} a_{0,0} & a_{0,1} & a_{0,2} \ a_{1,0} & a_{1,1} & a_{1,2} \ \end{array} \right]
The Matrix class provides the implementation of a general unsymmetric matrix. The data for the matrix is stored in a 1d double array of size numRows*numCols with the data for 
located at j*numRows + i in the 1d array. This is similar to the ordering of a Fortran 2d array and will permit calls to numerical Fortran libraries, e.g. BLAS, for certain method calls at a future stage. At present no subclassing is permitted (THIS MAY CHANGE), the reason for this is that the Matrix objects are envisioned to be small scale matrices primarily used for the passing of data between objects in the system. To allow subclassing could reduce the efficiency of the program due to the manner in which virtual functions are implemented.\

To construct a Matrix with numRows = {nrows}, and numCols = {ncols} and all coefficients equal to
. The memory for storage of the data is found at the location pointed to by {data}. Note that this memory must have been previously allocated and it must be of appropriate size, erroneous results and segmentation faults can occur otherwise. No additional memory is allocated for the storage of the data.

Zero's out the Matrix, i.e. sets all the components of the matrix to
. The method tests for the type of Matrix, to see whether the performance can be improved by avoiding having to call the overloaded (i,j) operators if the Matrix is of type genMatrix.
