> Matrix class that wraps a  FieldMatrix<T> matrix, which should be transformed to
reduced row echelon format.
> See: http://en.wikipedia.org/wiki/Row_echelon_form
> Example:
> RowReduce({{2, 0, -1, 0, 0},{1, 0, 0, -1, 0},{3, 0, 0, -2, -1},{0, 1, 0, 0, -2},{0, 1,
-1, 0, 0}}) 
> gives:
> {{1,0,0,0,-1},
>  {0,1,0,0,-2},
>  {0,0,1,0,-2},
>  {0,0,0,1,-1},
>  {0,0,0,0,0}}
