Example

// initialize an encoder
let encoder = VectorTileEncoder()

// create some attributes
var atts = [String: Attribute]()
atts["some_key"] = Attribute.attString("some_value")

// polygon geometry "well known text"
let wkt = "POLYGON ((0 0, 4096 0, 4096 4096, 0 4096, 0 0))"

// add the geometry and it's attributes as a "feature"
encoder.addFeature(layerName: "land", attributes: atts, geometry: wkt)

// encode to Mapbox vector tile
let data :Data = encoder.encode()
