Class
    Foam::XiGModel

Description
    Base-class for all Xi generation models used by the b-Xi combustion model.
    See Technical Report SH/RE/01R for details on the PDR modelling. For details
    on the use of XiGModel see \link XiModel.H \endlink. The model available is
    \link instabilityG.H \endlink
