Applicant manager/add new applicant

Implemented applicant adding method, related tests, service and DAO layers
Cannot be accomplished. Only String[] type are accepted by annotation parameters "consumes" and "produces"
http://docs.spring.io/spring/docs/3.1.x/javadoc-api/org/springframework/web/bind/annotation/RequestMapping.html#consumes()
so, the declaration like this "consumes = MediaType.APPLICATION_JSON" will not compile
