public class CommonSerDesSequential
extends Object
Common de/serialization for plain binary and compressed binary form 4
 which both used to walk the cas using the sequential, incrementing id approach
 
 Lifecycle:  
   There is 0/1 instance per CAS, representing the FSs at some point in time in that CAS.
 
   Creation:  
     serialization (for delta serialization, 
       the csds made when deserialization was done is reused, if available
       Updates cannot add to the reachables).
     non-delta deserialization
     delta deserialization uses previous one
 
   Reset: 
     CAS Reset
     API call (for optimization - used after all delta deserializations into a particular CAS are complete.
 
   Logical constraints:
     - delta de/serialization must use an existing version of this,
        -- set during a previous non-delta de/serialization
        -- or created just in time via a scan of the cas
