Implement Apply() that accepts GUIDS only.  Implement API to allow applicants to apply for a position.
Add route to obtain job-specific job applicants.
Allow multiple ways to inject the repo.
AcceptApplication() now returns a JobApplication and GetApplicants retuns a list of Guids.  Comment unit tests in order to compile.
JobApplication only stores IDs instead of entire objects.  Alter code to take advantage of this fact.
Add mongo-specific JobApplication. Resharper cleanup.  Manually add Guids / ObjectIds to applications.  Add new maps.
Must now get the Applicants using the collection of Applicant IDs and the job applicant repo.
