Generates a property, which is a singleton value accessed via the Universe.

Usage

domain! { EXAMPLE_DOMAIN }
property! { static EXAMPLE_DOMAIN/THING: i32 }
property! { static EXAMPLE_DOMAIN/NON_DEFAULT: i32 = 42; }
fn main() {
    EXAMPLE_DOMAIN.register();
    THING.register();
    let universe = v11::Universe::new(&[EXAMPLE_DOMAIN]);
    {
        let mut val = universe[THING].write().unwrap();
        *val = 90;
    }
    assert_eq!(90, universe.get(THING));
}
