Recycle Bin Review

Hi Julio,

I've completed the Recycle Bin section for the Dev Guide. Would you be able to review this new section and confirm that the section is written accurately? I based most of the content off your Recycle Bin presentation you presented at the North America Symposium.

You can view the rendered chapter [here](https://github.com/codyhoag/liferay-docs/blob/trash-feature/devGuide/en/chapters/07-using-liferay-frameworks.markdown), just search for the *Implementing the Recycle Bin* section. Let me know if you have any questions or concerns.
