``shape_based_thrust``
======================
Functionalities for shape-based low-thrust trajectory design.

This module provides the functionality for creating shape-based low-thrust trajectory design legs.
Without using any numerical propagation, this generates a preliminary low-thrust trajectory using
relatively simple (semi-)analytical methods.
For background information on the methods, see [1]_.
