Class
    turbulentTemperatureCoupledBaffleFvPatchScalarField

Description
    Harmonic fixed value boundary condition for temperature, to be used
    for heat-transfer on back-to-back baffles.

    If my temperature is T1, heat conductivity K1 and neighbour is T2,K2

    both sides get fixedValue (K1/dx1*T1 + K2/dx2*T2)/(K1/dx1+K2/dx2)

    Example usage:
        myInterfacePatchName
        {
            type                compressible::turbulentTemperatureCoupledBaffle;
            neighbourFieldName  T;
            K                   K; // or none
            value               uniform 300;
        }

    Needs to be on underlying directMapped(Wall)FvPatch.

    Note: if K is "none" looks up RASModel and basicThermo, otherwise expects
    the solver to calculate a 'K' field.

    Note: runs in parallel with arbitrary decomposition. Uses directMapped
    functionality to calculate exchange.

    Note: lags interface data so both sides use same data.
    - problem: schedule to calculate average would interfere
    with standard processor swaps.
    - so: updateCoeffs sets both to same Twall. Only need to do
    this for last outer iteration but don't have access to this.
