Diagnose convectively unstable gridboxes

Convection is activated in gridboxes with conditional instability. This is diagnosed by checking for any tropopsheric half level where the saturation moist static energy is lower than in the boundary-layer level. In gridboxes where this is true, convection is activated if either: there is convective instability - the actual moist static energy at the tropospheric level is lower than in the boundary-layer level, or, the relative humidity in the boundary-layer level and lowest tropospheric level exceed a set threshold (rhbl).
