+   The base class for frames. Every derived class from this class
+   must belong to some "major" class type and it must have an unique
+   id for itsself. Even if it is a base class it must have a unique id.
+
+   How does this work. We have an int for the Frame id. In the int
+   itsself we but the majorid as well.
+   The Start codes are all multiple of 2 so for example
+   0..127   belongs to FRAME UNK
+   128..255 belongs to FRAME RAW
+
+   So we can with a simple shift operation find out the major class
