        Wrapper

Known Subclasses:

Wrapper for python objects that need to be stored in event contexts and be retrived again from them
Quick note on how this works:
The actual *python* object has only 3 attributes which redirect into the wrapped C objects:
_impl   The wrapped C object itself
_attrs  This is a special pn_record_t holding a PYCTX which is a python dict
        every attribute in the python object is actually looked up here
_record This is the C record itself (so actually identical to _attrs really but
        a different python type

Because the objects actual attributes are stored away they must be initialised *after* the wrapping
is set up. This is the purpose of the _init method in the wrapped  object. Wrapper.__init__ will call
eht subclass _init to initialise attributes. So they *must not* be initialised in the subclass __init__
before calling the superclass (Wrapper) __init__ or they will not be accessible from the wrapper at all.
