CHANGE LOG:
-----------
* v3.2
* v3.2 (8 Mar 2019)
- New rotation functions, including the generation of Wigner-d matrices (thanks to Alex J. Yuffa).
- Add recurrence formula of Ishioka (2018) sometimes leading to faster transforms, especially for large sizes.
- New recurrence formula of Ishioka (2018) leading to faster transforms, especially for large sizes.
see https://doi.org/10.2151/jmsj.2018-019
- Easier configuration, with better detection of intel MKL.
* v3.1 (11 Oct 2018)
- Removed Robert formulation functions. Use `shtns_robert_form()` instead.

\section Speed
SHTns does not implement any "fast" algorithm. However, timings with other Spherical Harmonic Transform tools (including a fast algorithm)
show that <b>SHTns performs much faster than any other</b>. Furthermore, even at large sizes, the fast algorithm we tested does not seem to be willing to take the lead.

Since v3.2, SHTns implements the new recurrence relation of <a href="https://doi.org/10.2151/jmsj.2018-019">Ishioka (2018)</a>, leading to faster transforms, especially for large transforms.
