Added support for LocalDate and LocalDateTime
- does not make it so that swagger-springmvc absolutely requires a Java 8 runtime
Added support for flattening complex type request params.
- Simply add the @BeanParam annotation to a complex type request parameter in your Spring controller
  methods and the Swagger document that is generated for your operation will show a request param
  for each attribute in the complex type as opposed to just showing a complex model type. This change
  makes it so that individual text fields can be shown in Swagger UI as opposed to a text area.
