Types

Builder([symmetry, conservation_law, ...])	A tight binding system defined on a graph.
Site(family, tag[, _i_know_what_i_do])	A site, member of a SiteFamily.
HoppingKind(delta, family_a[, family_b])	A pattern for matching hoppings.
BuilderLead(builder, interface[, padding])	A lead made from a Builder with a spatial symmetry.
SelfEnergyLead(selfenergy_func, interface, ...)	A general lead defined by its self energy.
ModesLead(modes_func, interface, parameters)	A general lead defined by its modes wave functions.
FiniteSystem(builder)	Finalized Builder with leads.
InfiniteSystem(builder[, interface_order])	Finalized infinite system, extracted from a Builder.

Abstract base classes
