Message:

Introduce Adaptive-Implicit vertical advection option to the trunk. This is code merged from branches/2018/dev_r9956_ENHANCE05_ZAD_AIMP (see ticket #2042). The structure for the option is complete but is currently only successful with the flux-limited advection scheme (ln_traadv_mus). The use of this scheme with flux corrected advection schemes is not recommended until improvements to the nonoscillatory algorithm have been completed (work in progress elsewhere). The scheme is activated via a new namelist switch (ln_zad_Aimp) and is off by default.
