Nested pvproperty which allows decorator usage in parent class

Without using this for the SubGroups, using @subgroup.prop.getter causes the parent class to see multiple pvproperties - one defined on the subgroup, and one returned from pvproperty.getter. This class fixes that by returning the expected class - the parent (i.e., the subgroup)

Bonus points if you understood all of that.

… scratch that, bonus points to me, I think.

getter(get)	Usually used as a decorator, this sets the getter in the PVSpec.
putter(put)	Usually used as a decorator, this sets the putter in the PVSpec.
scan(*args, **kwargs)	Periodically call a function to update a pvproperty.
shutdown(shutdown)	Usually used as a decorator, this sets shutdown in the PVSpec.
startup(startup)	Usually used as a decorator, this sets startup in the PVSpec.

Attributes
