#TWTiledSpriteNode
A sprite node which will take a single or multiple textures display the textures tiled within a give size.
The node inherites from SKSpriteNode and makes use of a SKCropNode and SKSpriteNodes to create a node of exactly the right size without distorting the picture.
When multiple textures are given each tile within the node is given a random texture.
The example creates a tiled node from 4 textures and places it in a scene. The node can be resize by tapping and dragging anywere on the screen.
