}
Make a {@link Cesium3DTile}. This uses the content's tile's constructor instead
of importing Cesium3DTile. This is to avoid a circular dependency between
this file and Cesium3DTile.js
@param {Implicit3DTileContent} content The implicit content
@param {Resource} baseResource The base resource for the tileset
@param {object} tileJson The JSON header for the tile
@param {Cesium3DTile} parentTile The parent of the new tile
@returns {Cesium3DTile} The newly created tile.
