Parallel Systems for Entity Components

Features:

• Automatic execution of the systems in parallel. Follows Rust ownership rules. Depends on the order the systems are started.
• Component storage is abstract behind the trait. One can use vectors, hashmaps, trees, or whatever else.
• New components can be registered at any point from user modules. They don't have to be POD.
• No unsafe code! No virtual calls, low overhead.

Example system:

schedule.run1w1r(|p: &mut Position, s: &Speed| {
    *p += *s;
});
