* Fluent interface aspect provides an easy way to reuse "chain" interface for classes
* Basically, it uses around method to intercept all public setters in the class that implements
* special marker interface FluentInterface. Then it checks the return value for setter, if it's null,
* then advice replaces it with reference to the object "$this".
