This macro creates a new children group with the given amount of worker callbacks, and a closure that will be executed when a message is received.

Example

let children = children! {
    // the default redundancy is 1
    redundancy: 100,
    action: |msg| {
        // do something with the message here
    },
};

let sp = supervisor! {};
let children = children! {
    supervisor: sp,
    redundancy: 10,
    action: |msg| {
        // do something with the message here
    },
};
