Relay style pagination for Juniper.

This library provides the a `RelayConnection` struct, which can be returned in a Juniper GraphQL

schema and implements the [relay connection interface][spec].

## Example

```rust

#[derive(GraphQLObject)]

struct Foo {

  id: i32,

}

impl RelayConnectionNode for Foo {

    type Cursor = i32;

    fn cursor(&self) -> Self::Cursor {

        self.id

    }

    fn connection_type_name() -> &'static str {

        "FooConnection"

    }

    fn edge_type_name() -> &'static str {

        "FooConnectionEdge"

    }

}

RelayConnection::new(first, after, last, before, |after, before, limit| {

    let sql = format!("SELECT (id) FROM foo WHERE id > {after} AND id < {before} LIMIT {limit}");

    let edges: Vec = run_query(sql);

    Ok(edges)

})

```
