Subject: [PATCH] Remove `Data` types from the interface (#163)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
* Add properties to `Object`
* Add properties to `FiniteTileLayer`
* Add properties to `Layer`
* Add properties to `ImageLayer`
* Add properties to `ObjectLayerData`
* Remove `data()`; Replace `map()`
* Add properties to `LayerTile`
* `MapWrapper` -> `map_wrapper!`
* Fix examples/tests
* Limit visibility of data types
* Make `Tile::collision` public again
* Doc tweak
