Klein-Gordon operator.

Compute the covariant Klein-Gordon operator on a color std::vector.

For 0 <= j_decay < Nd, the laplacian is only taken in the directions other than j_decay.

Chi := (mass_sq + 2*(Nd[-1]) * Psi - sum_{mu ne j_decay} [ U_mu(x) * Psi(x+mu) + U^dagger_mu(x-mu) * Psi(x-mu) ]

Arguments:

Parameters

u	Gauge field (Read)
psi	Lattice field (Read)
chi	Lattice field (Write)
mass_sq	square of the mass term (Read)
j_decay	'left out' direction (Read)
