Persistent Object Interface.
[plug imp] 
This interface is used to store/restore attributes of an object. An IPlugController can implement this interface to handle presets. The gui-xml for a preset control looks like this: 
The tag data="Preset" tells the host to create a preset controller that handles the 3 values named "preset control", "store preset", and "remove preset".
The class ID must be a 16 bytes unique id that is used to create the object.
This ID is also used to identify the preset list when used with presets.
