JavaScript Inheritance Implementation

I'm not used to develop in Javascript but, as a fan of programming languages and object-oriented paradigm, my friend Otavio Avila and I decided to develop a kind of inheritance in JavaScript. He is a very experienced javascript developer and html coder, with helped me a lot with my lack of knowledge in these areas. You can check more about it in http://jsii.googlecode.com.
