Unable to get content negotiation to work with EasyRdf. More refactoring.
This app contains two similar, but different, approaches to displaying hours from WorldCat Institutional Registry's RDF API. The 'typemapped' version uses EasyRdf's class-type mapping to add convenience methods and more MVC-like structure. The 'basic' version mostly uses RDF graph traversal. Added a tiny bit of RDFa to the 'basic' version.
