* New routines in version 2.10:
* alm2map_spin: synthesis of maps of arbitrary spin
* map2alm_iterative: iterative analysis of map
* map2alm_spin: analysis of maps of arbitrary spin
* healpix_modules: meta-module

* parse_check_unused: prints out parameters present in parameter file but not used by the code.
* Improved routines:
* query_strip: the inclusive option now returns all (and only) the pixels overlapping, even partially, with the strip
* query_disc: when the disc center is on one of the poles, only the pixels overlapping with the disc are now returned.
