A hacked edition of Retrofit 2.0.2.

This is kind of for fun...

1. I added two annotations for type and method and apis of retrofit can share the annotations annotated a type:

   @FixField: Provide a fixed field to be posted with other dynamically passed in fields. @GeneratedField: Generated a field when a post request will be made.

2. Add new support of Mock Server. You can simply use the raw response data to mock a server response like this:

       @Override public Call<List<Contributor>> contributors(String owner, String repo) {
         return delegate.returningRawResponse(getJsonResponse()).contributors(owner, repo);
       }
       private String getJsonResponse(){
           // Eg. [{"login":"Jake", "contributions":1234},{"login":"John", "contributions":1234}]
           return ...;
       }

3. Add support of TypedFile. So when you want to upload a file, simply do it like this:

   public interface FileUploadService {
     @Multipart
     @POST("upload")
     Call<ResponseBody> upload(@Part("description") RequestBody description,
                               @Part TypedFile typedFile);
   }
   
   ...
   
   Retrofit retrofit = new Retrofit.Builder()
       .baseUrl("http://www.println.net/")
       .addConverterFactory(new TypedFileMultiPartBodyConverterFactory())
       .addConverterFactory(GsonConverterFactory.create())
       .build();
    
   FileUploadService service = retrofit.create(FileUploadService.class);
   TypedFile typedFile = new TypedFile("aFile", filename);
   String descriptionString = "This is a description";
   RequestBody description =
           RequestBody.create(
                   MediaType.parse("multipart/form-data"), descriptionString);
    
   Call<ResponseBody> call = service.upload(description, typedFile);
   call.enqueue(...);

   Name of the file to be uploaded will be used to retrieve the MediaType if you don't explictly set it. The retrieve of MediaType is still uncompleted.
