Usage
To encode an array of latitude/longitude pairs:
>> Polylines::Encoder.encode_points([[38.5, -120.2], [40.7, -120.95], [43.252, -126.453]])
=> "_p~iF~ps|U_ulLnnqC_mqNvxq`@"
To decode a polyline into an array of latitude/longitude pairs:
>> Polylines::Decoder.decode_polyline("_p~iF~ps|U_ulLnnqC_mqNvxq`@")
=> [[38.5, -120.2], [40.7, -120.95], [43.252, -126.453]]
