The core identity class for managing attributes, relationships, reactions, and properties. This class represents the "me" instance, which is the core identity object. You only need to pass a username when creating a new instance of `Me`, and this username will automatically become the identity of the `me` instance. Once an instance is created, you can interact with it by managing attributes, relationships, reactions, and properties using the methods provided.

// Creating a new Me instance
let me = new Me("suiGn");
