Package maptile provides types and methods for working with web mercator map tiles. It defines a tile as:

type Tile struct {
    X, Y uint32
    Z    Zoom
}

type Zoom uint32

Functions are provided to create tiles from lon/lat points as well as quadkeys. The tile defines helper methods such as Parent(), Children(), Siblings(), etc.
