- introduce variables ngX_o2 = ngX/2 where X = p,j,z
- replace all ngX/2 call by a call to ngX_o2
- compiler should optimize it anyway but can we trust it?

- takes as input ref. density temp etc.
- performs the transformation from dimensionless to physical units
- completely optional, everything can be postprocessed as well.
- new option for std output where the fluxes are in MW

- new_prob.sh creates a small environement with everything needed to run the first simulation
- parameter files and minimal python analyzing scripts are now present in basic_script

add the new magnetic tuners
have a consistent writing with capital k
