fix up package reference location in proj file
added a test project, because every good project needs one
extract an interface from Yobao for nancy automagic registration
refactor then remove netwonsoft references (uneeded), and add interface into ctor for automagic injection
make interface public
extract inferface (same reason as for Yaboa class)
remove uneeded registration (as they are now automagically done by Nancy) and add some placeholders if registration must be manually controlled (for later)
