/**
* The interface for ISO box. All Boxes inherit from this interface.
* Generate() and Write() are needed to be called to produce a complete box.
*
* Generate() will generate all the data structures and their size.
*
* Write() will write all data into muxing output stream (ISOControl actually)
* and update the data which can't be known at Generate() (for example, the
* offset of the video data in mp4 file).
*
* ISO base media format is composed of several container boxes and the contained
* boxes. The container boxes hold a list of MuxerOperation which is implemented
* by contained boxes. The contained boxes will be called via the list.
* For example:
* MovieBox (container) ---> boxes (array of MuxerOperation)
* |---> MovieHeaderBox (full box)
* |---> TrakBox (container)
* |---> MovieExtendsBox (container)
*
* The complete box structure can be found at 14496-12 E.2 "The‘isom’brand".
