/**

 *  Namespaced object
 *
 */
if (typeof SGL == 'undefined') { var SGL = {}; };
SGL.user = {
    addQuickNote: function() {
        alert('Quick note ajoutée');
    }
}

/**
 *  Entity object
 *
 */
SGL.user.User = function(name) {
    this.name = name;
}
SGL.user.User.prototype = {
    giveMyName: function() {
        alert('My name is ' +this.name);
    },

    setAge: function(age) {
        this.age = age;
    },

    giveMyAge: function() {
        alert('I am ' +this.age +' years old');
    }
};

SGL.user.addQuickNote();
var currentUser = new SGL.user.User('Julien');
