Strongly-typed, compile-time mediator.

## Documentation

See the documentation [on docs.rs](https://docs.rs/noon)

## Example

```rust

use noon::mediator::{Mediate, MediatorBuilder};

// Create message types

struct NewUserRequest { id: i32 };

struct NewUserResponse { total_users: u32 };

struct SendUserEmail { id: i32, msg: String };

struct NewUserLogin { id: i32 };

async fn foo() {

    // Create a mediator

    let mediator = MediatorBuilder::new()

        .add_handler(|x: NewUserRequest| {

            // get total users

            NewUserResponse { total_users: 13 }

        })

        .add_async_handler(|x: SendUserEmail| async move {

            // send email

            true

        })

        .listen_for::()

        .add_notification_receiver(|x: &NewUserLogin| {

            println!("User {} logged in!", x.id);

        })

        .build();

        

    mediator.notify(&NewUserLogin { id: 5 });

    let response = mediator.handle(NewUserRequest { id: 5 });

    println!("There are now {} users in the system", response.total_users);

}

let mediator = MediatorBuilder::new()

    .build();

```
