``transfer_trajectory``
=======================
Functionalities for multiple-leg interplanetary transfer trajectories.

This module provides the functionality for creating transfer trajectories consisting of
multiple transfer legs separated by transfer nodes. In particular, this allows defining multi-gravity assist
transfers with high-thrust legs, low-thrust legs or a mix of the two.
