Commit 3f70b4498e116bf89ea2230e4a6b081d8d240bc3 - Add option 'two_sidebands' to trace_out
- allows to specfiy only the mode corresponding to freq \omega
and automatically also trace out the modes corresponding to -\omega
- should also work for several modes
- added corresponding tests to entanglement_evaluation_test
