→OpenURL parsing and storing
Once the OpenURL is parsed with the ropenurl library, the data is stored in internal Umlaut classes, which are generally used subsequently to deal with the request data.
A bit confusingly, Umlaut's own Request (an ActiveRecord which represents a parsed OpenURL request, and other persistent state related to Umlaut's handling of that OpenURL request) should not be confused with the Rails ActionController::Request class (which represents the complete details of an the current 'raw' HTTP request, and is not stored persistently in the db).
So the first thing the resolve action does is pass the incoming HTTP request details to the Umlaut Request#new_request method, which will ''''either'''' create a new Request, or recover an already created Request from the db--in either case return a Request matching the OpenURL.
