Add path tiling utilities

Introduce the iterator types used to traverse and slice a
GeoCoordinates sequence to tiles:
* Add TilingIterator to convert the GeoCoordinates to a TileKeys
* Add AdjacentPairIterator to iterate over the adjacent pairs
* Add LineSliceIterator type to slice the path from point A to point B
* Add various helper functions to ease the iterators creation
Add a Bresenham's line algorithm used to generate tiles over a grid
