about the class to be put in the array can only be taken
after the construction of the parent class.

- The implementation of TFile throughput and info sending was
  just sending 'regular' samples about the activity of the single TFile
  instance that happened to trigger an activity in the right moment.
- Now TMonaLisaWriter keeps internally track of every activity
  and regularly sends summaries valid for all the files which had
  activity in the last time interval.
- Additionally, it's now finalized the infrastructure able to measure
  and keep track of the file Open latency. A packet is sent for each
  successful Open, sending the measures of the latencies for the
  various phases of the open. Currently exploited fully by TAlienFile
  and TXNetFile. Easy to report from other TFiles too.
- Now, the hook for the Close() func triggers sending of a packet
  containing various information about the performance related to that
  file only.
- Added support also for performance monitoring when writing

The background is the following. While working on the PROOF code I found
that enumerating TList is an inconvenient and a long operation, I had to
write the same code all over the place and make duplications. I tried
to use STD algorithms with it, namely std::for_each, and failed.
I therefore decided to enable std::for_each algorithm for ROOT 
Containers/Iterators by making as few as possible changes, without rewriting
iterators at all. Now with only two simple lines of code one is able to
iterate through a container:

TIter iter(&list);
for_each(iter.Begin(), TIter::End(), SEnumFunctor());

or

for_each(iter.Begin(), inter_end, SEnumFunctor());

where iter_end could be an iterator to a middle of the container.

After I had changed Iterators so that they could be used with std::for_each,
I decided to go further and did some more changes. As a result,

  - I have updated CINT implementation of some algorithms (they look now
    more or less better in terms of the standard),

  - TList and TObjArray can be now used with std::for_each, std::find_if,
    std::count_if (probably with some more algorithms. I've listed here
    only what has been *checked* by me). Other containers will be supported
    in a next patch.

  - A test program has been added: $ROOTSYS/test/stressIterators.cxx

  - A tutorial macro has been added: $ROOTSYS/tutorials/cont/TListAndSTL.C

Patch has been verified on Linux, MacOS X, Solaris 10 i386 and Windows.

    TObject *obj = array.At(i);                                        
                                                                       
By default the TRefArray 'points' to the current process and can only    
receive object that have been created in this process.                 
To point the TRefArray to a different process do:                      
    TRefArray array( processId );                                      
                                                                       
For example, if 'obj' is an instance that was created in the different 
process and you do:                                                    
    TRefArray array( TProcessID::GetProcessWithUID( obj ) );           
Then                                                                  
    array.Add(obj);                                                  
is correct (obj comes from the process the array is pointed to       
while                                                                
    TObject *nobj = new TObject;                                     
    array.Add(nobj);                                                 
is incorrect since 'nobj' was created in a different process than the
one the array is pointed to.  In thi case you will see error message:
     Error in <TRefArray::AddAtAndExpand>: The object at 0x... is not registered in the process the TRefArray point to (pid = ProcessID../....)

Three new methods have been implemented:

   Int_t   RescanLibraryMap();

Force a scan along the dynamic path again and load the *.rootmap files
in case the (DY)LD_LIBRARY_PATH has changed.

   Int_t   ReloadAllSharedLibraryMaps();

Reload for the loaded shared libraries their rootmap files.
This assumes that the library foo.[dll,a,so] has a rootmap named foo.rootmap.

   Int_t   UnloadAllSharedLibraryMaps();

Unload the rootmap entries for the loaded shared libraries.

I did not add anything to TSystem::SetDynamicPath() but in principle
the user should invoke after that operation RescanLibraryMap().

class, we now use the highest possible class version as the current
version of the class.  Practically, we update the class version
when reading new (higher versioned) StreamerInfo until the Class
is actually used (i.e. TClass::GetClassVersion is call directly
or indirectly).

In particular, if a file has several StreamerInfos for the same
versioned class, we will use the highest version number as the
'current' class version (as opposed to the lowest until now).

        TTree, TH1, TEventList, TEntryList, TGraph2D
(and hence their derived classes).

The instances of those classes are now added automatically 
to the current directory only when Constructe'd with arguments or Clone'd
and to the directory they are read from when their are stored
directly in a TKey. [Note: the default constructor never adds
the object to the current directory]

The directory auto add can still be disabled for instance
of TH1 and TGraph2D by setting TH1::AddDirectory.

Additionally one can disable the directory auto add for
a specific class by doing:

    TClass::GetClass("myclass")->SetDirectoryAutoAdd(0)

However you might want to also be able to restore the
behavior in which case you ought to do:

    TClass *cl = TClass::GetClass("myclass");
    ROOT::DirAutoAdd_t func = cl->GetDirectoryAutoAdd();
    cl->SetDirectoryAutoAdd(0);

TROOT::ReadingObject is marked as deprecated.. It is still
set (as it was) but is no longer used by the above mention
classes.

NOTE:  One side effect of this change, is that instnace 
of TTree, TH1, TEventList, TEntryList, TGraph2D that are
retrieved from a TMessage (i.e. from a socket) no longer
auto register themselves to the current ROOT directory.

Add a new optional parameter to TDirectory::Append: 'replace'
If replace is true (the default is false), the Append will
first remove from the directory any existing object and
print the message:

   Replacing existing OldClass: thename (Potential memory leak).

Add a new option parameter to TDirectory::CloneObject: 'autoadd'
If autoadd is true (the default), CloneObject will call the
object 'DirectoryAutoAdd' function (if any)

In TDirectory::CloneObject add support for multiple inheritance
from TObject where TObject is not the left most base class.

Fix memory leak in TGraph2D::operator= (and add TGraph2D::Clear)

Cleanup some documentation
