Not implemented:

[nange]

I'd like to try: h3ToGeo, h3ToGeoBoundary, h3kRing.

[nange]

I'll continue to take: h3IsValid, h3GetResolution, h3EdgeLengthM, h3EdgeLengthKm.

[nange]

I'll contine to take: h3GetBaseCell, h3HexAreaM2, h3HexAreaKm2, h3IndexesAreNeighbors, h3ToChildren, h3ToParent.

[nange]

I'll continue to take: h3ToString, stringToH3, h3IsResClassIII, h3IsPentagon, h3GetFaces, h3CellAreaM2, h3CellAreaRads2 .

[nange]

I'll continue to take: h3_to_center_child, h3_exact_edge_length_m, h3_exact_edge_length_km, h3_exact_edge_length_rads, h3_num_hexagons, h3_line, h3_distance, h3_hex_ring, h3_get_unidirectional_edge.

Hi @ariesdevil , I didn't find out the document about h3_edge_angle. Could you please provide a Ref or more infomation?
