JooseX.Class.SimpleConstructor - a trait for class, making the 'new' keyword optional during instantiation

SYNOPSIS

    Class('Some.Class', {

        trait : JooseX.Class.SimpleConstructor,

        has : {
            ...
        },

        methods : {
            ...
        }

    })

    // no need in `new`
    var instance = Some.Class()

    var check = instance instanceOf Some.Class // true

DESCRIPTION

JooseX.Class.SimpleConstructor is a very simple trait, which makes the new keyword optional for instantiation. The class constructor will just return a new instance every time. This trait should be applied last among all your traits, modifying the constructor behavior.
