* generating random Ex from a distribution

    - He_gas (Helium Gas)
    - O2_gas (Oxygen Gas)
    - Ti (solid titanium)

        - allow to add leaf as input/output from the detector file
        - calibration is supported with a token having the name of the
          leaf

fixing Z-dir calculation Beam random events (direction cosines), it used to be sytematically over-estimated

fixed Bug: switch from reading 1D to 2D profile for emittance use hist. Decoupling tokens energy and profile tokens

adding an offset (+2) to the strip calculation with the new method using Masks. This should be looked at further
