Tracking Methods

To each lattice element one can vary the method used to track particles through the element. This is useful, among other things for optimizing speed and/or accuracy.

q1: quadrupole, l = 0.6, ..., tracking_method = runge_kutta

Some possibilities:

**bmad_standard**   Fast, thick element formulas.
**symp_lie_ptc**    Symplectic Lee integration tracking.
**taylor**          Taylor map.
**linear**          Linear tracking.
**custom**          Tracking with custom code.
**runge_kutta**     Track through fields.
etc...
