Tour 2: A tight-binding model on a square lattice
-------------------------------------------------
Let us now consider free fermions on a Bravais lattice.
We will set up a square lattice with the nearest
neighbour hopping using the ``BravaisLattice`` class of TRIQS, compute its
density of states (DOS) and then plot it by using again the ``oplot`` function.
