1.4 New and Modified Commands

• The bunched_beam and bunched_beam_moments commands now support specification of the (common) spin vector.
• The modulate_elements command now supports time- and pass-based modulation delays, as well as a convenience factor for the modulation amplitude.
• The centroid, final, output, and sigma output files from run_setup include spin-related quantities when spin tracking is enabled.
• Optimization of spin-related quantities is supported.
• The particle_tunes command has the option to include spin tune.
• The moments_output command has the option to force e₁ > e₂.
