    // at the time of writing there's no actual API for the intel map to retrieve scoreboard data,
    // but it's still useful to plot the score cells on the intel map


    // the S2 geometry is based on projecting the earth sphere onto a cube, with some scaling of face coordinates to
    // keep things close to approximate equal area for adjacent cells
    // to convert a lat,lng into a cell id:
    // - convert lat,lng to x,y,z
    // - convert x,y,z into face,u,v
    // - u,v scaled to s,t with quadratic formula
    // - s,t converted to integer i,j offsets
    // - i,j converted to a position along a Hubbert space-filling curve
    // - combine face,position to get the cell id

    //NOTE: compared to the google S2 geometry library, we vary from their code in the following ways
    // - cell IDs: they combine face and the hilbert curve position into a single 64 bit number. this gives efficient space
    //             and speed. javascript doesn't have appropriate data types, and speed is not cricical, so we use
    //             as [face,[bitpair,bitpair,...]] instead
    // - i,j: they always use 30 bits, adjusting as needed. we use 0 to (1<<level)-1 instead
    //        (so GetSizeIJ for a cell is always 1)

	// - https://docs.google.com/presentation/d/1Hl4KapfAENAOf4gv-pSngKwvS_jwNVHRPZTTDzXXn6Q/view?pli=1#slide=id.i22
	// at the time of writing there's no actual API for the intel map to retrieve scoreboard data,
	// but it's still useful to plot the score cells on the intel map


	// the S2 geometry is based on projecting the earth sphere onto a cube, with some scaling of face coordinates to
	// keep things close to approximate equal area for adjacent cells
	// to convert a lat,lng into a cell id:
	// - convert lat,lng to x,y,z
	// - convert x,y,z into face,u,v
	// - u,v scaled to s,t with quadratic formula
	// - s,t converted to integer i,j offsets
	// - i,j converted to a position along a Hubbert space-filling curve
	// - combine face,position to get the cell id

	//NOTE: compared to the google S2 geometry library, we vary from their code in the following ways
	// - cell IDs: they combine face and the hilbert curve position into a single 64 bit number. this gives efficient space
	// and speed. javascript doesn't have appropriate data types, and speed is not cricical, so we use
	// as [face,[bitpair,bitpair,...]] instead
	// - i,j: they always use 30 bits, adjusting as needed. we use 0 to (1<<level)-1 instead
	// (so GetSizeIJ for a cell is always 1)
