Detailed Description

Null B field - for special cases where we need a valid object.

Simply returns 0,0,0,0,0,0 for all field components. Used for teleporter or specifically written tracking routines that may ignore the 'field' but still need a valid object that can be called by Geant4 in order to fit into its scheme.
