/*! Creates a geometry information describing a HEALPix map with an
Nside parameter \a nside. \a weight contains the relative ring
weights and must have \a 2*nside entries. The rings array contains
the indices of the rings, with 1 being the first ring at the north
pole; if NULL then we take them to be sequential. Pass 4 * nside - 1
as nrings and NULL to rings to get the full HEALPix grid.
\note if \a weight is a null pointer, all weights are assumed to be 1.
\note if \a rings is a null pointer, take all rings
