+OpenLayers 3 should provide an API that makes it easy to accomplish common use cases. People who do not need to leverage the full functionality should be provided fast lanes for a leaner and easy to use configuration. Defaults should be set in the right places to avoid duplicated code.

+The layer source should not need a projection configuration - it should get it from the view. With the projection's extent, the layer source should be able to create a default tile grid.
