/**		/**
* Represents an object on a map, such as a POI, a building, a way or a boundary		* @brief Represents an object on a map.
.		*
		* An item holds the data for an individual item on a map, including its coordin
		ates and various attributes. The item
		* type specifies what the map item refers to, such as a POI, a building, a way
		or a boundary. There are also special
		* item types used internally, such as the various kinds of turn instructions. I
		tem types are internally represented as
		* numbers.
		*
		* Outside map implementations, items are generally retrieved from map rectangle
		s, and their methods are implemented by
		* the respective map driver. Items retrieved from a map rectangle are generally
		short-lived: a previously retrieved
		* item should be considered invalid when a new item is retrieved from the same
		map rectangle, or after its map
		* rectangle has been destroyed. After that, functions may segfault or return in
		valid data, and even the item itself
		* may have been deallocated.
		*
		* Actual behavior may differ between map implementations, but do not rely on an
		y behavior not covered by the above
		* interface contract. Exceptions apply, of course, for code that is limited to
		working with items from one particular
		* map (typically inside a map implementation).
