Typedef Documentation

using MagneticField = Acts::ConstantBField

This tests intend to check the behaviour of the navigator in cases where the straight-line approach for the layer resolval can fail. This is in particular the case with bent tracks in telesocpe-like geometries, and can be fixed by not doing the bounds check in the initial resolving.
