About the mincaps/maxcaps:
These have a center and radius-squared, describing the region

single healpix -- ie, more than MARGIN distance from any edge.
That is, the mincap is the small circle centered at (0.5, 0.5) in
the healpix and with radius = the distance to the closest healpix
boundary, MINUS the margin distance.
Below, we first check whether a new star is within the "mincap"
of any healpix. If so, we stick it in that healpix and continue.
Otherwise, we check all the "maxcaps" -- these are the healpixes
it could *possibly* be in. We then refine with
healpix_within_range_of_xyz. The maxcap distance is the distance
to the furthest boundary point, PLUS the margin distance.
