The Principal Components Analysis class
=======================================
In many applications of various fields of research, the treatment of
large amounts of data requires powerful techniques capable of rapid
data reduction and analysis. Usually, the quantities most
conveniently measured by the experimentalist, are not necessarily the
most significant for classification and analysis of the data. It is
then useful to have a way of selecting an optimal set of variables
necessary for the recognition process and reducing the dimensionality
of the problem, resulting in an easier classification procedure.

TPrincipal is the implementation of one such method of
feature selection, namely the principal components analysis.
This multidimensional technique is well known in the field of pattern
recognition and and its use in Particle Physics has been documented
elsewhere (cf. H. Wind, <I>Function Parameterization</I>, CERN
72-21).

- New options to draw contours for 2-d histograms.
  The contour option "CONT" is now a pure 2-D option. It is not based
  on the surface/lego algorithms.
  This option computes now a set of points stored in a list of TGraph objects.
  The points in the TGraph are sorted, such that one contour can be drawn
  with one fill area. In addition, when the option "List" is specified,
  the list of generated TGraph objects is stored in a TObjArray with the
  name "contours". This TObjArray is accessible via gROOT->GetListOfSpecials().
  When the option "CONT" is used, one can superimpose new contours on top
  using the options "CONT1", "CONT2" or "CONT3".
  The previous algorithm used by the option "CONT" is still available
  as option "CONT4".
  For example, the following call
     h2->Draw("contzlist");
  produces:
    - a picture with surface colors to delimitate each contour
    - the color palette.
    - a list of the boundary points for each countour.
  The points used to draw the contours are saved in the TGraph format
  and are accessible in the following way:
  TObjArray *contours =
           gROOT->GetListOfSpecials()->FindObject("contours")
  Int_t ncontours = contours->GetSize();
  TList *list = (TList*)contours->At(i); //where i is a contour number
  list contains a list of TGraph objects. For one given contour, more than
  one disjoint polyline may be generated. The number of TGraphs per
  countour is given by list->GetSize().
  Here we show only the case to access the first graph in the list.
    TGraph *gr1 = (TGraph*)list->First();

containers.
The streamer that is produced automatically by rootcint for STL container
break one of the newer features of ROOT.  I.e. it does NOT allow to reuse
the same object to read several time from disk (this feature is usefull in
trees).
For this feature to work correctly the streamer need to make sure to clean
the object before reading from file. (empty list, delete pointers, etc..)

The kMAXFOUND parameter limit for the EvalInstance() member function
was increased to 200 for version 2.24.05 (along with the appropriate
change in TFormula). However, the size of the fCodes, fCumulSize, and
fIndexes arrays (declared in the header) and the fIndex array (declared
in the constructor) should be increased to 200 as well.
(Thanks to Gene Van Buren for reporting the inconsistency)

The kMAXFOUND parameter is now declared in TFormula.h and kMAXCODES
is set to kMAXFOUND in TTreeFormula.
