```x1 = uniqrows(X)

Then, the matrix given is:

x1 = (
1,0,0,0,0,0,0,0\
1,0,0,0,1,0,0,0\
1,0,0,1,0,0,0,0\
1,0,1,0,0,0,0,0\
1,1,0,0,0,0,0,0\
1,1,0,0,1,0,0,1\
1,1,0,1,0,0,1,0\
1,1,1,0,0,1,0,0   )

But what I need is:

x2 = (
1,0,0,0,0,0,0,0\
1,0,1,0,0,0,0,0\
1,0,0,1,0,0,0,0\
1,0,0,0,1,0,0,0\
1,1,0,0,0,0,0,0\
1,1,1,0,0,1,0,0\
1,1,0,1,0,0,1,0\
1,1,0,0,1,0,0,1   )

Of course, this can be done easily for just this matrix, but the problem is that
I need the correct matrix as part of an estimation command (thus, the matrices
can be different everytime, dependent on the dataset at hand), so I need a sort
of general way to ensure the matrix  is always sorted correctly. However, I've
not find a working strategy yet.

Kind regards, Alex
