file, the following 3 files are checked at start up;
     $ROOTSYS/etc/class.rules (or ROOTETCDIR/class.rules)
     $HOME/class.rules
     ./class.rules 

Add a short form to the I/O customization rules.  The 2 syntaxes are:
Short form:
   [type=Read] classname membername [attributes=... ] [version=[...] ] [checksum=[...] ] [oldtype=...] [code={...}]
Long form:
   [type=Read] sourceClass=classname [targetclass=newClassname] [ source="type membername; [type2 membername2]" ]
        [target="membername3;membername4"] [attributes=... ] [version=...] [checksum=...] [code={...}|functionname]

Add a new element to the rules: attributes
Currently the only 2 attributes supported are 'Owner' and 'NotOwner' which
indicates to whether the data member 'owns' the objects it is pointing to.

Store all the rules defined for all the classes stored in a TFile in the
same list as the StreamerInfo.   The rules are stored as a sub list of
TObjString and the list is named 'listOfRules'

TClass: when creating or registering a class we now alway remove the 
any part of the class name that is a default template argument of a STL
container. (i.e. the allocator in pair<int,vector<int,allocator> >
which becomes pair<int,vector<int> >)

TList: Improve the performance of RemoveLast by customizing it for TList.

of Emulated Object inheriting from compiled class).
This avoids memory leaks when the user data model relies on polymorphism
(and we are not using the library) and avoid splicing if the data is copied.

Details:

TStreamerInfo::New inserts the address of the creating TStreamerInfo into
the object.  This address is inserted in each emulated that does not inherit
from an emulated class and is positioned after all the base classes (which
are compiled classes).   A derived class will set this value inside each
of its emulated base class.

TStreamerInfo::Destruct and the new method TStreamerInfo::GetActualClass
use this information to detect the TStreamerInfo actually used to create
the object and hence run the proper emulated destructor.

In TFormLeafInfo which an issue where a data member which is an STL
container was not properly found.

make it such that an emulated collection of pointers can become owner of its content.

The default, for backward compatibility and to avoid double delete (at the expense
of memory leak), the container of pointers are _still_ not owning their content
__unless__ they are a free standing container (i.e. itself not contained in another
object).

To make a container of pointers become owner of its content do something like:

      cl = TClass::GetClass("ObjectVector<LHCb::MCRichDigitSummary>");
      if (cl && cl->GetStreamerInfo()) {
         TObject *el = cl->GetStreamerInfo()->GetElements()->FindObject("m_vector");
         if (el) el->ResetBit(TStreamerElement::kDoNotDelete);
      }

For MakeProject, use file->GetStreamerInfoCache() instead of the TClass GetStreamerInfo.

MakeProject now implements a move constructor for each classes.   For the implementation, we 'use' the 'copy constructor' until the C++ compilers properly support the official move constructor notation.   Implementing a move constructor avoid having to delete and reconstruct resource during a std::vector resize and avoid the double delete induced by using the default copy constructor.

the 2 distincts pointers point to a single object and more cases where we are 
missing the StreamerInfo and need to guess whether the symbol represent an enum,
a class or a namespace.

To use genreflex, call MakeProject with the "genreflex" option, for example:

         file->MakeProject(libdir,"*","NEW+genreflex");

To make sure the library created by MakeProject does not double delete an object,
tell the StreamerElement representing one of the pointers pointing to the object
to never delete the object.  For example:

      TVirtualStreamerInfo *info = (TVirtualStreamerInfo*)file->GetStreamerInfoCache()->FindObject("HepMC::GenVertex");
      if (info) {
         TObject *el = info->GetElements()->FindObject("m_event");
         if (el) el->SetBit(TStreamerElement::kDoNotDelete);
      }

Note that MakeProject only uses the list of StreamerInfo internal to the TFile (as opposed
to the global list of StreamerInfo used by the regular I/O operations) and thus the change
must be done on the StreamerInfo in file->GetStreamerInfoCache().

To make sure that the class emulation layer of ROOT does not double delete an object,
tell the StreamerElement representing one of the pointers pointing to the object
to never delete the object.  For example:

      TClass *clGenVertex = TClass::GetClass("HepMC::GenVertex");
      if (clGenVertex) {
         TObject *el = clGenVertex->GetStreamerInfo()->GetElements()->FindObject("m_event");
         if (el) el->SetBit(TStreamerElement::kDoNotDelete);
      }

Details:

TClass:
Correct the order in which the RealData is created for emulated class (base class must be last).

TBaseClass:
Improve stability in case where the base is reloaded (by using TClassRef instead of TClass*)

MakeProject:

Improve support for classes that are used (as scope or as template parameter) but do not have
a StreamerInfo in the file (because no object of that type is saved) by passing around the
list of extras streamerinfos while hold the artificial temporary StreamerInfo we create for
those classes.

Use the bit TStreamerElement::kDoNotDelete to decide whether to delete a sub object held
in a pointer data member or not.

In TMakeProject::UpdateAssociativeToVector correctly handle the case where the type
is actually a nested type of a template class instance.  Also now this functions
stips the default template parameter from STL containers.   It adds std:: in front
of the name of STL classes if needed.

Add support for genreflex in MakeProject.   With the option "genreflex", MakeProject
produce the additional file dirnameSelection.xml and populate the file
dirnameProjectInstances.h.  In MAKEP, genreflex is called instead of rootcint.

In MakeProject, fixed a double delete of the StreamerInfos.
