Description:
    Defines the interface the client must implement which
    provides the data definitions for performance counting.
    This interface would normally be implemented with a
    singleton class. It will be called from both the
    client side performance monitor as from the DLL implementation,
    which is why I pulled out the interface def to a separate lib unit.
