Class
    Foam::CloudStateFieldRef
 
Description
    Wrapper for a reference to a dynamic Lagrangian field. It provides
    convenient access consistent with that of the derived fields so that
    expressions involving both kinds of field are readable. It also ensures
    that old-time fields are maintained for a sub-mesh for the duration of the
    inner correction iterations.
