+ Remove NPTagManager class

+ Update MUGAST geometry so rectangular detectors are now taken
  into account

+ Change permissions for MUGAST analysis files
+ Update ControlSimu.C macro

 - optional token, keeping retrocompatibility
 - allow to use "beam" at rest as source for gamma cascade

+ Update trapezoid geometry for gaspard

  - Now follow the new logique
  - Less file
  - Updated geometry

  - Method BuildPhysicalEvent method without argument were declared but
    not defined

  detector

+ ongoing work for adapting GaspardTrackerAnnular to the new
  scorer scheme

 - Delete the actual geometry
 - Clear the Detector Manager
 - Reload Geometry file

For this to work a couple of thing has been done:
 - InitializeRootInput now need an extra SetBranchAddress to tell the
   tree that the previous address is no longer in use
 - Scorer can not be cleared, so need to be retrieved in case of a
   reloading. If they do not exist they are created
 - This is done using the new CheckScorer static method from VDetector

* Advancing Tiara Barrel Simulation, now working (still to be tested
extensively)

* adding Dictionnary for VDetector class to avoid error message in root

* outputted incorrectly

* committed prototype

  it was giving linking errors in NPAnalysis
  + the main changes have been to declare the AddHisto1D and AddHisto2D
    methods in 'public' instead of 'private' in VSpectra.h
  + some cleaning for including headers in NPLib/T*Spectra.{h,cxx}

* introductiong VSpectra a template virtual class from which derived the
* TSpectra classes

* Fixing minor bug in NPBeam and NPReaction

* Detector are now put in alphabetical order

* Updating copyright
* adding AnnularS1Physics class
