Parent class for all views extensions. All classes that inherit from that class must define a constant named EXTENSION_ID that is unique for each extension type, and is used when retrieving an extension from a view. When choosing the identifier to use with your class, you must look at other defined identifiers to avoid collision. In addition, some ranges are reserved for specific usage:
- 0x0 to 0xFFFF: reserved for IOLink
- 0x10000 to 0xFFFFFFFF: reserved for external modules by the IOLink team
- Other values: user defined extensions
