0.6.0

🚨 Breaking Changes

• Cheetah elements are now subclasses of torch.nn.Module, where the parameters should always be torch.Tensor. This makes cheetah a fully differentiable simulation code. (see #11)
• The cell keyword argument of cheetah.Segment has been renamed to elements.
• Element and beam parameters must now always be passed to the constructor or set afterwards as a torch.Tensor. It is no longer possible to use float, int or np.ndarray. (see #11)

🚀 Features

• Convert from Bmad lattices files (see #65) (@jank324)
• Add proper transfer map for cavity (see #65) (@jank324, @cr-xu)
• Twiss parameter calculation and generate new beam from twiss parameter (see #62) (@jank324, @cr-xu)
• Saving and loading lattices from LatticeJSON (see #9) (@cr-xu)
• Nested Segments can now be flattened (@jank324)
• Ocelot converter adds support for Cavity, TDCavity, Marker, Monitor, RBend, SBend, Aperture and Solenoid (see #78) (@jank324)

🐛 Bug fixes

• Fix dependencies on readthedocs (see #54) (@jank324)
• Fix error when tracking ParameterBeam through segment on CPU (see #68) (@cr-xu)

🐆 Other

• Add CHANGELOG.md (see #74)
• Improved documentation on converting Marker object into cheetah (see #58) (#jank324)
