/**
    The CIMFlavor class implements the concept of the CIM qualifier flavor that
    encapsulates the propagation and override rules for qualifiers.
    The propagation rules define whether a qualifier
    may be propagated from classes to derived classes, or from classes to
    instances.  The override rules define whether or not derived classes may
    override a qualifier value or whether it must be fixed for an entire
    class hierarchy.

    The possible values are: OVERRIDABLE, TOSUBCLASS, TOINSTANCE,
    TRANSLATABLE, DISABLEOVERRIDE, ENABLEOVERRID, RESTRICTED and DEFAULTS.
    The flavor is a set of zero or more of these possible values.
