That is correct 'project(A, r1, r2)' returns a sub matrix, in this case a 
'matrix_range'.
If you want to assign to a whole row or column then the simple
        row(A, r) = u;
will suffice.
If you want to assign to a specific sub vector of a matrix then you will need 
to use either
matrix_vector_range or matrix_vector_slice
