+        In SICS there is the to find out what an
+        object is capable of at runtime. If this has been done a general
+        way to access those capabilities is needed. In order to do all
+        this each SICS-object is required to carry an object descriptor
+        struct as first parameter in its class/object struct. Additionslly
+        it is required to initialize this struct to something sensible.
+        
+        This file defines this struct. Additionally a few functions of
+        general use are prototyped.
