Development branch related to CNRS-0 and NOC-1 action of 2014 work plan: simplify and improve the lateral diffusion and dissipation in NEMO/OPA

change the way the eddy diffusivity and viscosity are specified and controlled by the user.

(1) introduce Beckers et al. (2000) compact stencil in the cross-isoneutral direction in triads formalism ;
(2) introduce in both iso-neutral operator the Method of Stabilizing Correction (Lemarié et al. (2012) ;
(3) implement bilaplacian iso-neutral operator (Lemarié et al. (2012)

The associated branch is 2014/dev_CNRS0_NOC1_LDF
