	/** @brief CCTMXTiledMap knows how to parse and render a TMX map.

	It adds support for the TMX tiled map format used by http://www.mapeditor.org
	It supports isometric, hexagonal and orthogonal tiles.
	It also supports object groups, objects, and properties.

	Features:
	- Each tile will be treated as an CCSprite
	- The sprites are created on demand. They will be created only when you call "layer->tileAt(position)"
	- Each tile can be rotated / moved / scaled / tinted / "opacitied", since each tile is a CCSprite
	- Tiles can be added/removed in runtime
	- The z-order of the tiles can be modified in runtime
	- Each tile has an anchorPoint of (0,0)
	- The anchorPoint of the TMXTileMap is (0,0)
	- The TMX layers will be added as a child
	- The TMX layers will be aliased by default
	- The tileset image will be loaded using the CCTextureCache
	- Each tile will have a unique tag
	- Each tile will have a unique z value. top-left: z=1, bottom-right: z=max z
	- Each object group will be treated as an CCMutableArray
	- Object class which will contain all the properties in a dictionary
	- Properties can be assigned to the Map, Layer, Object Group, and Object

	Limitations:
	- It only supports one tileset per layer.
	- Embeded images are not supported
	- It only supports the XML format (the JSON format is not supported)

	Technical description:
	Each layer is created using an CCTMXLayer (subclass of CCSpriteBatchNode). If you have 5 layers, then 5 CCTMXLayer will be created,
	unless the layer visibility is off. In that case, the layer won't be created at all.
	You can obtain the layers (CCTMXLayer objects) at runtime by:
	- map->getChildByTag(tag_number);  // 0=1st layer, 1=2nd layer, 2=3rd layer, etc...
	- map->layerNamed(name_of_the_layer);

	Each object group is created using a CCTMXObjectGroup which is a subclass of CCMutableArray.
	You can obtain the object groups at runtime by:
	- map->objectGroupNamed(name_of_the_object_group);

	Each object is a CCTMXObject.

	Each property is stored as a key-value pair in an CCMutableDictionary.
	You can obtain the properties at runtime by:

	map->propertyNamed(name_of_the_property);
	layer->propertyNamed(name_of_the_property);
	objectGroup->propertyNamed(name_of_the_property);
	object->propertyNamed(name_of_the_property);
