An Atom library prototype. Its purpose is to explore the cost of us supporting Atom as the default input and output format of RESTful controllers. Only the constructs necessary for representing comment feeds and entries have been implemented. Its output are valid Atom 1.0 documents. The test contains examples of how to make feeds and entries.
