2D square lattice tight bind model, with external B field, Peierls substitution

tight binding model with B field use Peierls substitution and a paper Peierls substitution for magnetic Bloch bands

test.py

(1)increase the system size L

L=8

(2)increase the B field interval

BBins=64

(3)half the size with symmetry

2*np.pi to np.pi
