[Wannier] non-zero overlap matrix elements between wannier orbitals EXAMPLE03

[Mithra Chan]

Dear all,

I just test EXAMPLE03 provided wannier90. I just added "hr_plot = true" the
silicon.win and then run wannier90. However, I got an non-zero matrix
overlap elements between wannier orbitals on the same site. In my
understanding, they should be zero. Is my understanding wrong or something
else wrong? Thanks a lot.

Best regards,

Mithra
