  Description     : C++ library for Healpix representation of spherical data

Healpix projections are used, particularly in astronomy and physics, for displaying and manipulating full-sphere data that
vary as a function of lat/long or RA/dec.

Debian includes a C library (libchealpix0 and libchealpix-dev) that implements a subset of functions for
manipulating Healpix data. But that library is rather sparse as compared to the much fuller set of functions
available in the C++ version of the library (and, of course, the functions that the C library does provide are not
particularly easy to incorporate into programs written in an object-oriented C++ manner, particularly if exception
handling is used). Using the C library to emulate some of the functions that are present in the C++ library can be 
done, but it requires rather detailed knowledge of the mathematics of the Healpix projection, which an ordinary
user would not have.

This request is for the full C++ library.
