 * Puts an array of tiles or a 2D array of tiles at the given tile coordinates in the specified
 * layer. The array can be composed of either tile indexes or Tile objects. If you pass in a Tile,
 * all attributes will be copied over to the specified location. If you pass in an index, only the
 * index at the specified location will be changed. Collision information will be recalculated
 * within the region tiles were changed.

 * @function Phaser.Tilemaps.Components.PutTilesAt

 *
 * @param {(number[]|number[][]|Phaser.Tilemaps.Tile[]|Phaser.Tilemaps.Tile[][])} tile - A row (array) or grid (2D array) of Tiles or tile indexes to place.
 * @param {number} tileX - The x coordinate, in tiles, not pixels.
 * @param {number} tileY - The y coordinate, in tiles, not pixels.
 * @param {boolean} recalculateFaces - `true` if the faces data should be recalculated.
 * @param {Phaser.Tilemaps.LayerData} layer - The Tilemap Layer to act upon.
