TGLPadHistpainter/TGLAxisPainter/TGLLegoPainter - new hist-painter
infrastructure.

First version of TGLLegoPainter, the new class to support different types
of legos:
gl + lego(1)/lego2 + pol/cyl/sph
gl + lego3

TGLUtil : Small auxilary classes.

IMPORTANT: this lego painter is still experimantal and works only if
it's enabled in system.rootrc. By default, TGLHistPainter is used now.
To enable this new system the line:

Plugin.TGLHistPainter: * TGLHistPainter RGL "TGLHistPainter(TH1*)"

Must be replaced with

Plugin.TGLHistPainter: * TGLPadHistPainter RGL "TGLPadHistPainter(TH1*)"

in $ROOTSYS/etc/system.rootrc

New package to edit/create detector geometries

1. Using the geombuilder with a geometry from scratch:

root[0] new TGeoManager("test", "test geometry builder");
root[1] gGeoManager->Edit();

In this case forcing TGeoManager::Edit() is mandatory because the geometry cannot be yet drawn in the pad. There are few steps to create a valid geometry:
- create at least one material from the "Materials" shutter item category. Generally for creating objects, the interface is always in the TGeoManagerEditor in different categories - one should just provide a name and requested params.
- create a shape for the top volume within the "Shapes" category. For the moment the shapes that have editors are: Box, Trd1, Trd2, Tube, Tube segment, Cone, Cone segment and Sphere. More to come...
- create a medium from one of the existing materials from the "Medium" category. You will notice that some categories as: "Volume" and "Medium" are inactive at the beginning because at that time there is no material yet (for making a medium) and no shape (for making a volume). These categories are dynamically activated once all the required components are defined.
- create a volume from the "Volumes" category. You will notice that contrary to the other editors, the volume editor is opened in a tab, not transient - this is because it is more complex.
- go back to "General" category and select the newly created volume as the top one (you can do it also from the volume category)


This is just to start. To create really some hierarchy, one has to create several other volumes and the matrices to position them. Once this is done, use the volume editor interface to:
- add/remove daughters, change shape, edit position of daughters
- change visualization settings
- divide the volume (only if there are no daughters yet)

The TGeoManagerEditor GUI allows:
- editing the geometry name/title, setting top volume, closing the geometry, exporting the geometry as .root or .C file
- creation of new elements (shapes, volumes, materials, media, matrices)
- editing existing elements (they can be browsed from transient dialogs)

IMPORTANT: To access the manager editor if this is not in the "Style" tab one can either:
- left-click on the top-right corner of the pad if something is drawn
- call gGeoManager->Edit()

2. Editing an existing geometry (probably you should start with this first)

- Just load the geometry in memory:
     root[0] .x $ROOTSYS/tutorials/rootgeom.C
-  draw some volume (if not already) then do View/Editor, then click on the top-right corner to get the manager editor. Clicking a volume will open the volume editor in the Style tab, but here I could not get rid of the TAttFill editor that is useless for volumes.
- work with existing TGeoManagerEditor categories as explained at 1.

- Added protection to not create a TClass instance if the Reflex scope is not fully defined. There was a problem with a scope of a typedef in the STL hashtable.
- Fixes the problem of applying CintName() (basically removing std::) to the scope of enums
- Fixes the problem of defining by mistake primitives as tagnames when defining typedefs

 o) improved handling of batch, which now allows:

      >>> import ROOT
      >>> ROOT.gROOT.SetBatch( 1 )
      >>>

    to work as expected
 o) allow direct access to overloads with call "disp" on methods

void TTreeFilePrefetch::SetThreshold(Double_t t)
   // Static function to set fgThreshold
   // A new basket will not be registered in the cache if
   // the current (Tree entry < fEntryMin) > 100*fgThreshold
   // so t is more or less the percentage of baskets read to be considered in the cache
   // This algorithm eliminates branches where only a few baskets are processed

1. Mixtures components can now also be other materials/mixtures:
  TGeoMixture::AddElement(TGeoMaterial *mat, Double_t weight);
2. When elements are added via TGeoMixture::AddElement(TGeoElement *elem,...), the list of elements is kept.
3. Some fixes related to visualization within TGeoPainter

   // When clicking in the browser, the following action is performed
   // on this macro, depending the content of the variable TMacro.Browse.
   // TMacro.Browse can be set in the system.rootrc or .rootrc file like
   //     TMacro.Browse   :  Action
   // or set via gEnv->SetValue, eg
   //     gEnv->SetValue("TMacro.Browse","Print");
   // By default TMacro.Browse=""
   // -if TMacro.Browse ="" the macro is executed
   // -if TMacro.Browse ="Print" the macro is printed in stdout
   // -if TMacro.Browse is of the form "mymacro.C"
   //     the macro void mymacro.C(TMacro *m) is called where m=this macro
   //     An example of macro.C saving the macro into a file and viewing it
   //     with emacs is shown below:
   //        void mymacro(TMacro *m) {
   //           m->SaveSource("xx.log");
   //           gSystem->Exec("emacs xx.log&");
   //        }

A new option is planned in the very near future: possibility to see
the macro in the new ROOT editor currently being implemented by Bertrand.

  -support for TChain
  -Reuse the same cache when loading a new Tree

WARNING!!!!
==============================================
The TTree File cache is now set ON by default
==============================================

You can test the effect of the cache by setting
  mytree.SetCacheSize(0);  //default is 10000000 bytes
  mychain.SetCacheSize(0);

The cache has no negative impact on the performnace when reading
local files. It improves drastically the performance when reading
a remote file through a high latency network.

An improved version of TSpectrum class. There were two problems.
1. The extrapolation of the right hand part of the spectrum above the edge
(range). Now it works and I do not see any problem.
2. Due to high level of noise in the examples from Sergey the estimation of
the background snathed lower spikes in the spectrum and as a consequence there
remained rests of background after its subtraction. In some cases it was
detected as false peaks. In new version I have included the estimation of
background with simultaneous smoothing, which removes this problem.
However for smooth data and for the detection of small peaks on big background
I recommend to exclude Markov smoothing (set markov parameter to false) when
calling the SearchHighRes function.
