Please add user-defined object comparison support

[qilinO-o]

User-defined object comparison is currently supported by as-test and as-pect.
Simply, as-test do it with a JSON string compare, something like this:

this.left.set(JSON.stringify<T>(this._left));
this.right.set(JSON.stringify<T>(equals));

And as-pect do it with a somehow reflection mechanism.
I think user-defined object comparison is crucial for the unit test framework. Hope it will be supported soon.
