"""Quantum field theory example
* https://en.wikipedia.org/wiki/Quantum_field_theory
This particular example is a work in progress. Currently it calculates the
scattering amplitude of the process:
    electron + positron -> photon -> electron + positron
in QED (https://en.wikipedia.org/wiki/Quantum_electrodynamics). The aim
is to be able to do any kind of calculations in QED or standard model in
SymPy, but that's a long journey.
