An augmented system matrix is said to be in reduced row echelon form (RREF) if the following are true:
1. If a row has non-zero entries, then the first non-zero entry is 1. This is known as the leading one.
2. If a column contains a leading one then all other entries in that column are zero.
3. If a row contains a leading 1, then each row above contains a leading 1 further to the left.

  void reduce(T A, int coefficientColumns)
  Puts the augmented matrix into RREF.

- Method Detail
  - reduce
```
void reduce(T A,
            int coefficientColumns)
```
    Puts the augmented matrix into RREF. The coefficient matrix is stored in columns less than coefficientColumns.
    
    Parameters:
    
    A - Input: Augmented matrix. Output: RREF. Modified.
    
    coefficientColumns - Number of coefficients in the system matrix.
