                                         PythonUFOHelasCallWriter

The class for writing Helas calls in Python, starting from HelasWavefunctions and HelasAmplitudes.

Includes the function generate_helas_call, which automatically generates the Python Helas call based on the Lorentz structure of the interaction.
