Please add fastClass inheritance compharison

[dotnetwise]

Please add fastClass https://github.com/dotnetwise/Javascript-FastClass with its goods and bads as you have fairly reviewed other peers as well.
As for the record it does support private methods if it is used like this

var A = function (val) {
    this.val = val;
}.define({
    method1 = function (x, y, z) {
        this.x = x;
        this.y = y;
        this.z = z;
      }
});

var B = A.fastClass(function (base, baseCtor) {
        function privateMethod(z) { 
            this.z = "some private value" + z;
        }

    return function () {
        this.constructor = function (val) { baseCtor.call(this, val) },
        this.method1 = function (y, z) {
            base.method1.call(this, 'x', y, z);
                        privateMethod.call(this, z);
        }
    };
});

var b = new B("b");
b.method1("y", "z");
b.z; //"some private value z"

When I wrote this originally, TypeScript wasn't out yet, but yes when I have the time I'll update this.

Sorry, by mistake I have saved the same issue twice. I have re-edited the issue so you can include my fastClass inheritance with its pros and cons among the others.
