Added
- Physical System Wrappers as a new feature to process actions and states directly in the environment. A decent introduction can be found in the [GEM cookbook](https://github.com/upb-lea/gym-electric-motor/blob/nightly/examples/environment_features/GEM_cookbook.ipynb) (Paragraph 2.8)
- The externally excited synchronous motor (EESM) has been added to the GEM-toolbox.
- The environments of the EESM can be instantiated with the following keys: "{Cont|Finite}-{CC|TC|SC}-EESM-v0",
Changed
- The MotorDashboard has received a "initialize()" method to initialize the plots below a specific cell.
- The MotorDashboard is now compatible with the "%matplotlib widget" backend. Therefore, GEM is now compatible with the integrated jupiter notebook execution of Visual Studio Code
Fixed
- If multiple converters were used and the time constant tau was changed from its default values, it was possible that the values of tau were different in each converter
