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

* Fixing minor bug in NPBeam and NPReaction

* Updating copyright
* adding AnnularS1Physics class

 - In the case of multiinteraction in the same volume, the scorer was keeping only the last energy deposit, instead of summing them
 - The threshold has been move in the Read sensitive and is no longer in the scorer, as the energy deposit can be down in multiple step each of them below threshold and be ignored if the threshold is applyed individually.

 - putting the update date 2009-2013
 - Adding some missing liscence header
 - moving some #ifndef to avoid copy of comment
 - fixing minor compilation bug in TSpegPhysics

 - Renaming of private member of Initial Condition
 - Beam energy was not set in Read Configuration

 - fixing couple of bug
 - remove some warning
 - enhance performance

 - Only one read configuration file method
 - lighter code
 - possibility to use TH1F for cross section shoot

 - Add associate class in NPL
 - Add Function in NPL

Some code clean up has been done as well (cosmetic change for the most)
