From Philippe
This patch restores and enhances TTree::Scan previous behavior regarding arrays.
It nows always (unless user request otherwise) print all the requested elements
of all the arrays. The printing of multi-dimensional array is now done in a
linear, non-synchronized fashion. In particular this means that selection on
2D arrays (including array within a TClonesArray) might not print the correct
instance of the arrays (in case of using arrays of un-even dimension)
You can now limit the number of element in the array by using the string option 'lenmax=dd':

From Philippe
I enhanced TTree::Scan so that instead of having
t3333->Scan("PtGen","Type==13");
being always equivalent to
t3333->Scan("PtGen[0]","Type[0]==13");
TTree::Scan will now print all the requested elements of any array (as TTree::Draw does).
TTree::Principal has been similarly updated (but not tested).
TTreeFormula has also been updated to remove a bad side-effect of the boolean operation optimization. In case like
analysis->Scan("Lept_1","Lept_1>=0&&Lept_2!=0");
if Letp_1[0] was negatif then the Lept_2 branch was not read from file.

From Philippe:
This patch solves 2 problems.
If a simple tree was made the friend of a chain, the simple tree was loaded using the 'entry in the tree (inside the
chain)' instead of the 'entry in the chain'. This resulted in ONLY the first part of the simple tree to be used (over
and over again)!
TTree::Scan (Query and CopyTree) could not handle the case where a TChain was made a friend of a TTree (and problably
more cases of uneven length chain friends). This was
because, it never detected that a new file was open since it only looked a the main Tree (and none of its friend). In
consequence the formula were not updated when they should.
