Kubo-Tanimura hierarchy and the correspoding propagator can be created from the configured SBI and Hamiltonian. OpenSystem object has these attributes and it therefore deserves an implementation of the methods, such as get_KTHierarchy and get_KTHierarchyPropagator to enable an easy application of the HEOM theory on the Molecule and Aggregate objects.
