+* Description: 
+* This file contains the implementation of the ASN1 Set and Set-of object, 
+* as described in X208 Sections 22 and 23 and X209 Sections 16 and 17. The 
+* set object can contain an ordered series of zero, one or more other ASN1 
+* objects. The set-of object contains zero, one or more of the objects 
+* described in its definition. The data encodings of both these objects is 
+* identical. The ordering of the elements contained within set objects is not
+* significant.
+* The implementation of sets is pretty much the same as that for sequences 
+* (indeed it has started from a straight cut'n'paste) but there are some 
+* significant differences with regard to ordering of items within the set,
+* comparison and retrieval of items.
