	/** 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
	- Each tile can be rotated / moved / scaled / tinted / "opacitied"
	- 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 TextureMgr
	- 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 NSMutableArray
	- Objects can be created using your own classes or a generic 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 TMXLayer (subclass of CCSpriteSheet). If you have 5 layers, then 5 TMXLayer 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 (TMXLayer 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 TMXObjectGroup which is a subclass of NSMutableArray.
	You can obtain the object groups at runtime by:
	- [map objectGroupNamed: name_of_the_object_group];

	Each object is a TMXObject.

	Each property is stored as a key-value pair in an NSMutableDictionary.
	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];
