Changes to the REST engine: * The set of paths can now be applied compositioinally from different classes and modules. Each set appends to the previous. * Support for JAX-RS annotations: @QueryParam, @PathParam, @HeaderParam, @FormParam, @MatrixParam. This is in addition to the existing @ApiParam. * Documentation for a method can use either the legacy @MethodDescription or Swagger's @ApiOperation. * Various bug fixes when generating swagger documentation for parameter types. * Some more unit tests for Swagger document generation - notably for `KEndPoint`.
