Class
    Foam::SLGThermo

Description
    Thermo package for (S)olids (L)iquids and (G)ases
    Takes reference to thermo package, and provides:
    - carrier : components of thermo - access to elemental properties
    - liquids : liquid components - access  to elemental properties
    - solids  : solid components - access  to elemental properties

    If thermo is not a multi-component thermo package, carrier is NULL.
    Similarly, if no liquids or solids are specified, their respective
    pointers will also be NULL.

    Registered to the mesh so that it can be looked-up
