    • plots with lattices (automatic reload on changes)
    • reload on change
    • interpolation with s
    • table pretty printer
    • twiss/survey:
    • interpolation with s, cycle w/wo reset cumulative quantity, range extraction, append
    • twiss:
      • calculate beta max inside quadrupole, integral k*beta, normalized dispersion, transfer matrix in between points, 2D normalization matrix, partial integrals to compute Q', Q'
      • add errors from error tables
      • compute driving terms kernels
      • compute detuning factor
      • compute footprint based on detuning equations
    • survey:
      • redefine origin to any point (2D only)
      • compute rotation matrix
