  This module provides solvers for system-bath evolution using the
  HEOM (hierarchy equations of motion).
  
  See https://en.wikipedia.org/wiki/Hierarchical_equations_of_motion for a very
  basic introduction to the technique.
  
  The implementation is derived from the BoFiN library (see
  https://github.com/tehruhn/bofin) which was itself derived from an earlier
  implementation in QuTiP itself.
  
  For backwards compatibility with QuTiP 4.6 and below, a new version of
  HSolverDL (the Drude-Lorentz specific HEOM solver) is provided. It is
  implemented on top of the new HEOMSolver but should largely be a drop-in
  replacement for the old HSolverDL.
