Another lower level element returned by buildState is the selector map. Much like @ngrx/entity, the selector map is a simple object (associative array) that maps common names to selector functions.
As with the IEntityState interface, we have attempted to maintain naming compatibility with @ngrx/entity here, however also as with IEntityState we provide a lot more than @ngrx/entity does as well. Selectors are available for every state property managed by NgRx Auto-Entity.
