    * Ninja Physics Tile constructor.
    * A Tile is defined by its width, height and type. It's type can include slope data, such as 45 degree slopes, or convex slopes.
    * Understand that for any type including a slope (types 2 to 29) the Tile must be SQUARE, i.e. have an equal width and height.
    * Also note that as Tiles are primarily used for levels they have gravity disabled and world bounds collision disabled by default.
    *
    * Note: This class could be massively optimised and reduced in size. I leave that challenge up to you.
