LAST MODIFICATIONS

Stacking Manager:
 	The stacking manager is now responsible for the tracks selection. If the tracks in the staks are not desired partiles they are killed directly. This was done before by the stepping manager and costed more CPU time.
	The gamma particles are killed. It seems that some processes for gamma particles have a bug in the 8.0.2.p01 version of geant4. The consequence is a global time that goes back. One should contact them to check it.

DetectorConstruction:
	The ring anode was entirely built in the half or quarter detector view modes (cf command Detector/View ). This caused few problems with the geometry controler.


AtRestSpinPrecession:
	The spin precession at rest is not calculated if the magnetic field is (0,0,0). This "mute" problem caused crashed in the simulation under rare special conditions. The typical error when a (0,0,0) vector is used or when a vector is divided by zero leads to a "ZMxpvInifiteVector thrown" message.


PhysicsList:
	For simplicity the modular physics list was removed and everything is now in LEMuSRPhyiscsList.



SteppingAction:
	Some data about the killed particles (killed for looping in fields) are now printed out.


LEMuSRMultipleScattering:
	This class is now G4 independant and has its own ParticleChange.
