TEST	(	LocalizationTest	,
		RandomOnSiteEnergy
	)

1D crystal Randomize the on-site energies to be between 0 an 1 Fix the hopping terms to be 1 for the nearest neighbours and decaying as 1/r^3 Fix the dynamical terms to be 1 for the nearest neighbours and decaying as 1/r^3

calculate 1/two_particle_localization_length = - lim_{|n-m|--> infty} << ln|<m, m+a|G(z)|n, n+a>| >> / |n-m| where << ... >> represents the average over different configurations of disorder

In the current case, we let a = 1 and we want z.real to be at the center of the band
