* v2_00 - Desgagne M. - initial MPI version
* v2_10 - Desgagne M. - routine changed name to accomodate
* v2_10 high order hor. diffusion option
* v2_10 - J.P. Toviessi - reset V grid operator on call to hzd_abc
* v2_11 - Desgagne M. - remove vertical modulation
* v2_11 - M. Roch - diff. on phi instead of phi' at model lid
* v2_21 - Desgagne M. - control for diffusion on momentum only
* v2_31 - Desgagne M. - remove stkmemw
* v3_10 - Corbeil & Desgagne & Lee - AIXport+Opti+OpenMP
* v3_11 - Corbeil L. - new RPNCOMM transpose
* v3_20 - J. P. Toviessi - variable higher order diffusion operator
*
