Directions:
    Write a recursive function that will set he components of a
    matrix to all true.

Declaration:
    apmatrix<bool> matrix(10, 12, false);

Prototype:
    void trueMatrix(apmatrix<bool>& matrix, int row, int col);

Call:
    trueMatrix(matrix, 0, 0)

Code:
    void trueMatrix(apmatrix<bool>& matrix, int row, int col)
    {
        if(row < matrix.numrows() && col < matrix.numcols() &&
           !matrix[row][col])
        {
            matrix[row][col] = true;
            trueMatrix(matrix, row + 1, col);
            trueMatrix(matrix, row, col + 1);
        }
    }
