Class
    Foam::radiationCoupledBase

Description
    Common functions to emissivity. It gets supplied from lookup into a
    dictionary or calculated by the solidThermo:

    - 'lookup' : Read the patch emissivity field from the dictionary
    - 'solidRadiation' : Use the emissivity field mapped from the adjacent solid
