A lightweight, super fast, pure javascript event system that works in node and the browser.

  Set up a receiver channel....

    function callBack(d) {
        console.log(d);
    }

    Signals.receive("change", callBack);

    Signals.signaled("change", callBack);

    var payload = "I changed!";

    Signals.signal("change", payload);
    
        //  I changed!
    
    payload = "I have updates!";
    
    Signals.signal("update", payload);
    
       //  I have updates!

    Signals.dropReceivers("change");

    Signals.dropReceivers();

    function model() {
        var ID = null,
            slf = this;
        this.get = function() {
            return slf.ID;
        };
    };

    var mdl = model;

    mdl.prototype = Signals;
    
    mdl.constructor = model.constructor;

    mdl.prototype.set = function(val) {
        var slf = this;
        if(val && val !== slf.ID) {
          slf.ID = val;
          slf.signal("change", val);
        }
        return slf;
    }

    var Ident = new mdl();

    Ident.receive("change", function(d) {
        console.log("change signaled, new ID value: " + d);
    });

    Ident.set("ABC");  //  "change signaled, new ID value: ABC"

    var lg = Ident.get();
    
    console.log(lg);  // "ABC"

    Ident.set(123);   //  "change signaled, new ID value: 123"
      
    lg = Ident.get();
    
    console.log(lg);  // 123

    Ident.dropReceivers();
