the change from TRandom to TRandom3.
However, there is a problem with DrawTest (to be investigated)

This patch implements support for the accessing the collection object in
TTreeFormula:

//     Accessing collection objects
//     ============================
//
//  TTree::Draw default's handling of collections is to assume that any
//  request on a collection pertain to it content.  For example, if fTracks
//  is a collection of Track objects, the following:
//      tree->Draw("event.fTracks.fPx");
//  will plot the value of fPx for each Track objects inside the collection.
//  Also
//     tree->Draw("event.fTracks.size()");
//  would plot the result of the member function Track::size() for each
//  Track object inside the collection.
//  To access information about the collection itself, TTree::Draw support
//  the '@' notation.  If a variable which points to a collection is
prefixed
//  or postfixed with '@', the next part of the expression will pertain to
//  the collection object.  For example:
//     tree->Draw("event.@fTracks.size()");
//  will plot the size of the collection refered to by fTracks (i.e the
number
//  of Track objects).

This update improves the error message in case of failure.

This patch adds systematic test for the ability of TTree::Draw to draw TBits objects.
It also fixes all the bug discovered during the tests.
It also adds a test for split level 2.

This update to drawtest does the following:
        start moving toward using makefile
        reduce the text printed while running
        reduce the time as much as possible

array inside a TClonesArray when the TClonesArray is not split.
It also adds a test for reading variable size array inside a TClonesArray.
It also fixes a problem recently mentioned on roottalk where the formula
for not properly reading variable size array when the
variable size was indexed more there was more than one variable in the formula.

They are now considered by default as an array of numbers.  However if
they are used with an operator== or an operator!= and if the second argument
is also a string, the strcmp function will be used.  In addition, a direct call
of the function strstr is allowed.   The checks and error messages have been
improved for both the operator and strstr.
This update also corrects the problem where an expression was drawn multiple
times when using a fixed length array in string comparaison.
