  /** 
   * This class is intended to TAG immutable serializable classes.
   * When you have too identical user immutable classes in a serialization graph tree, they will be considered as a single entity
   * and reading the object tree would cause a single object reference also.
   * 
   * This is useful if for example you are serializing an object read from the database, and you have several identical instances 
   * on the tree. They will be all considered a single instance and JBossSerialziation will place then as references.
   * 
   * Classes implementing Immutable are required to provide a proper equals and a proper hashCode implementations.
