  //
  // Part 3: Data Links
  //
  // Data links are persistable references. Typically they will replace 
  // pointers from one object in the event to another, hence they have
  // the usual "pointer" syntax (op *, op ->, op !, ...)
  // (to be pedantic they have the moniker syntax as they don't define ++, --)
  // For example in Atlfast::Cell
  // class Cell {
  //   ...
  // private:
  //    std::vector<const HepMC::Particle*> m_particles;
  // };
  // m_particles would become
  //    std::vector<HepMCLink<Particle>::type > m_particles;
  //
  // To understand data links it is important to observe that the SG 
  // is not able to identify every single object in the event.
  // In particular individual elements of a container (the MyContObj 
  // in the vector above or the Particles in McEventCollection) are not
  // recorded individually into SG, only their owner (the container) is.
  // For this reason data links are supported by two class templates:
  //  DataLink<DATAOBJ> is a link to a data object i.e. an object
  //   identified by SG
  //  ElementLink<CONTAINER> is a link to an element of a container (which 
  //   in turn is a SG data object)
  // To make a DataLink persistable we need to provide its SG identifier 
  //  (its type and key). 
  // To make an ElementLink persistable we need two pieces of information: 
  //  i) the SG identifier (type/key) of the data object owning the element 
  // ii) the identifier of the contained object within the owner
  // For example when we write out a link to the third element of 
  // our vector<float> we want to write the SG id of the vector 
  // and the index (2) of the element in the vector
  //
  // Since the indexing mechanism of a container depends on the container
  // type we need to specialize ElementLink for different containers
  // Elements of STL sequences (lists, vectors, deques but also DataVector 
  // and DataList) are dealt with automatically. 
  // For other STL or STL-like containers, the data object designer (or the
  // client must "help" ElementLink identifying the type of container
  // Three macros in the header StoreGate/DeclareIndexingPolicy.h
  // are provided to this end:
  //  for sequences use CONTAINER_IS_SEQUENCE( MySequence )
  //  for sets use CONTAINER_IS_SET( MySet )
  //  for maps and related containers use CONTAINER_IS_MAP( MyMap )
  // 
  // It is also possible to define custom specializations of ElementLink
  //  for custom containers (e.g. GenParticleLink for McEventCollection). 
  //
  //Enough! Let's now create our first DataLink. It refers to the first
  // MyDataObj we recorded. DataLink constructors use references 
  // as input arguments
  //
  // DataLink referring to a storable object
  //
  DataLink<MyDataObj> dobjLink(*dobj);
  //since dobj is identifiable in the SG a reference to it is all we need
 
  SG::WriteHandle<MyDataObj> dobj2 (m_dobjKey2, ctx);
  dobj2 = std::make_unique<MyDataObj> (2);
 
  //Otherwise one could first create an empty link

  //and later on set it to refer to its target
  dobjLink2.toStorableObject(*dobj2);
 
 
  // Added Aug 30, 2001  HMA 
  // DataLink made from a key. This should work for either an object
  // already registered in the store, or an object that has a
  // persistency for it.  we use dobj3, which is an object registered with 
  // a key.
