genSpinLattice()

Lattice syten::IPEPS::Lat::U1::genSpinLattice	(	int const	width,
		int const	depth,
		double const	spint = 0.5,
		std::vector< char >	site_classes = {}
	)

Generates a uniform Heisenberg spin lattice with U(1)-Sz symmetry.

Parameters

width	unit cell width
depth	unit cell depth
spint	total spin on each site
site_classes	class of each site (tensor to be placed there)
