     Mixed boundary condition for temperature, to be used for heat-transfer
     on back-to-back baffles.
 
-    If my temperature is T1, neighbour is T2:

-    T1 > T2: my side becomes fixedValue T2 bc, other side becomes fixedGradient.
+    Specifies gradient and temperature such that the equations are the same

+    - refValue = neighbour value
+    - mixFraction = nbrKDelta / (nbrKDelta + myKDelta())

     Note: runs in parallel with arbitrary decomposition. Uses directMapped
     functionality to calculate exchange.
 
-    Note: lags interface data so both sides use same data.

-    this for last outer iteration but don't have access to this.
