Class
    Foam::functionObjects::properties
 
Description
    Storage for function object properties, derived from IOdictionary.
    Provides functionality to read/write state information (data required for
    smooth restart behaviour) and results to/from the state dictionary
 
    Note: cannot be accessed until after construction of thefunction objects,
    since the owner container functionObjectList is owned by time, and time owns
    [this] i.e. need to wait for time to be fully constructed.
