void StdFace_Tetragonal ( struct StdIntList *  StdI)

Setup a Hamiltonian for the square lattice.

Author
Mitsuaki Kawamura (The University of Tokyo)

(1) Compute the shape of the super-cell and sites in the super-cell

(2) check & store parameters of Hamiltonian

(3) Set local spin flag (StdIntList::locspinflag) and the number of sites (StdIntList::nsite)

(4) Compute the upper limit of the number of Transfer & Interaction and malloc them.

(5) Set Transfer & Interaction
