This release improves the dsgp4 API (providing easier API to propagate TLEs both in normal and batch mode) and introduces several tutorials for its use.
Basic tutorials focusing on:
* what a TLE object is, how to load TLE objects, and how to construct them from strings or dictionaries
* how to propagate TLEs (both in batch and normal mode, and single or multiple times)
* how to compute partial derivatives of SGP4 outputs w.r.t. inputs and/or TLE parameters, leveraging the autodiff support
Advanced tutorials focusing on spaceflight mechanics problems:
* similarity transformation (i.e., covariance transformation)
* 1st order covariance propagation
* gradient-based optimization
