[SciPy-Dev] [GSOC 2018 Project Thread]: Rotation formalism in 3 dimensions

[Aditya Bharti]

We do plan to create a tutorial with examples highlighting the major
functionality of the module and some common use cases, but its exact nature
and extent will depend upon how much time we have left after completing the
implementation (including docstrings and tests).

Best,
Aditya
