Function decorateRoads

decorateRoads(
    roads: RoadNetworkLike,
    world: World,
    input?: DecorateInput,
    ctx?: DecorateContext,
): PropPlacement[]
Places street furniture and rural props along a road network deterministically: street lights, hydrants, bins, benches and bus stops on urban sidewalks; traffic lights, stop signs and street name signs at junctions; speed limit signs; and along rural roads power lines on one side, mailboxes at lot frontages (or driveways), biome-matched fence runs, hay bales in the fields and the odd well. Props never stand in water, on the carriageway, or on top of each other.
Parameters
- roads: RoadNetworkLike
  A threejs-city RoadGraph, CityData.roads, or plain data of that shape.
- world: World
  The world (ground height, water and biomes).
- input: DecorateInput = {}
- ctx: DecorateContext = {}
Returns PropPlacement[]
Placements for Props (poles of one power line share a line id).
Example
```
const placements = decorateRoads(city.data()!.roads, world, { seed: 7, powerLines: { spacing: 40 } }, { frame: city.frame, lots: city.data()!.lots })
const props = await Props.create({ placements })
city.local.add(props.object)
```
