Cormac Relf 868904874a manually implement Default for *GroupStorage ... All the example code uses Default to create the db structs, but it turns out the *GroupStorage's `#[derive(Default)]` adds a trait bound of (e.g.) `DB__ + Default + HelloWorldDatabase` even though it never actually needs to call HelloWorldDatabase::default(). So if you didn't implement Default, then you couldn't be a salsa database struct.		2019-01-26 02:45:07 +11:00
