Structs
CellID uniquely identifies a cell in the S2 cell decomposition.
The most significant 3 bits encode the face number (0-5). The
remaining 61 bits encode the position of the center of this cell
along the Hilbert curve on that face. The zero value and the value
(1<<64)-1 are invalid cell IDs. The first compares less than any
valid cell ID, the second as greater than any valid cell ID.

Functions
ij_level_to_bound_uv returns the bounds in (u,v)-space for the cell at the given
level containing the leaf cell with the given (i,j)-coordinates.
