    对象定位（唯一键）注解 MetaFieldAnnotation

### example
test.io.jsen.meta.diff.Demo
test.io.jsen.meta.diff.GenericTest

```java
Map<String, String> map1 = new HashMap<>();
        map1.put("name", "jsen");
        map1.put("age", "12");
        Map<String, String> map2 = new HashMap<>();
        map2.put("name", "jack");
        map2.put("sex", "女");
        MetaObject diffObject = MetaContext.toMeta(
                new MetaDiffModel(new TypeToken<Map<String, String>>() {
                }, map1, map2)
        );
        Object nativeObject = MetaContext.toNative(diffObject);
