- adding a typedef of NPParticle into NPNucleus to solve
        backward compatibility
        - changing QFS and Reaction to match new terminology

        - NPNucleus will be renamed subsequently to NPParticle

Updating Scone, ChiNu and PISTA detectors

        - now takes into account cases of first and last step correctly
        - default value for reaction condition set to -1000

        - name convention in geant4 is different for g.s and excited
        state

nps
        - the flag is --random-seed

        - AnyAboveThreshold returning true even if no decay allowed
        - Causing beam to try to decay repeatly in simulation

        - If the lifetime section contained a special caracter

thickness was computed twice

Update/fix the 'LabCrossSection' option; this option is till in progress and currently works for special cases

        - Since the introduction of G4Region to simulate reaction it was
        impossible de reload a geometry without a segfault
        - Problem is convolutated and was fixed by preserving the world
        from the reload
        - Still an issue remain, we cannot change the branches of the
        output tree without a seg fault, need to be investigated

	- GetThetaWorldFrame (!!!!! This doesn't work)
	-GetPhiWorldFrame (it works)

fonction callable from root cint

* Added (Phi, LAB_Theta, LAB_Phi) angle branches filling, and simplification of change frame for emitted particles momentum
