Import an orthogonal tilemap from the Tiled map editor.

 *

This will create entities in the current scene representing all the tiles & objects in the tilemap. Each tile gets a tile component tag so you can find them later. Each tile also gets a grid component with the x/y/z grid coordinates in tile space.

*

All of the properties that are in the tilemap are set as components in each tile entity, and the property values are treated as JSON. More specific properties override less specific properties. The order of precedence for tile properties is:

 *
     *
  1. tile layer
    2.  *
  2. tile in tileset
    3.  *
  3. tileset
    4.  *
< *

The order of precendence for object properties is:

 *
     *
  1. object
    2.  *
  2. object layer
    3.  *
  3. tile in tileset
    4.  *
  4. tileset
    5.  *
*

A special "container" entity is also created with a container component tag that has the dimensions of the map in its size component.
