**[triqs/lattice]** Lattice tools
===============================

TRIQS comes with a couple of modules that allow to work with free fermions on Bravais lattices, with 
tight-binding hoppings.

   This part of the documentation largely is work in progress ...

Introductory example
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
