Log:
added flag to modify Septum magnetic field shielding length inside the prerun macro. Cohordinate system has z at the center of the Septum (z=69.91cm in lab cohordinate (normal z)). Two commands for positioning the high and low limit of the septum pipe magnetic shielding: /moller/field/setLowLim (default -44 cm (Shielding will need to be bigger than PREXI, so there will be accepted values <=-44cm))  /moller/field/setHighLim (default 44 cm , range >= 44 cm). These two commands will go in prex_prerun.mac macro. The gradiend of the field dBxdy is plotted in a TGraph and saved in the root file and the values on this TGraph is output on the screen at the end of the run. The model used is a simplified model that uses the shape of the Field outside the shielding as calculated from P. Brindza and assumes the same dumping of the shielding as seen with the PREXI magnetic shielding on the beam pipe. A full TOSCA calculation of the field is then suggested when a desired configuration is r
 eached to check the results.
