RSS Generator: Generate RSS 2.0 feed from an array of items

This class can be used to generate a RSS feed compliant with the version 2.0 of RSS specification.

The class is based on Paulius Lescinskas' Easy RSS class.

It can generate a complete RSS 2.0 feed passing an array of item definition arrays. The item arrays describe item properties such as the title, link URL, description and publication date.

The global properties of the feed can be set by assigning class variables with the same names. The supported feed properties are: the title, description, publication date, generator name, language and encoding.
