Modified Commands

• The run_setup command now optionally accepts the central momentum in MeV/c, instead of just $\beta\gamma$.
• The tune_shift_with_amplitude command was improved to provide second-order shifts as well as the tune spread for a specified range of amplitudes. These quantities may be optimized.
• Added computation of the minimum and maximum tunes for a specified range of momentum offsets. These values may be optimized.
• Optimization may now include the chromatic derivatives of the beta and alpha Twiss parameters.
• The load_parameters command will now accept a list of input files and will optionally ignore non-existent files.
• The lost-particles file (requested from run_setup), now includes the turn on which each particle is lost.
• Made changes that allow computing closed orbit for the momentum offset of the beam distribution and then starting the beam on that orbit. The changes are to the closed_orbit and track_beam commands.
• Optimization terms with zero weight are now ignored, instead of generating an error.
• Added disable control for optimization variables and co-variables.
• Added disable control for transmute_elements.
