版本更新说明： 1.0.0 完成基本功能; 1.0.1 全局变量的作用域从之前强制public改成只要非private即可; 1.0.2 修改 SaveHelper.bind(this, savedInstanceState)方法为SaveHelper.recover(this, savedInstanceState),只是重命名， 以便于理解; 去掉当内存被回收去调用recover方法时，却没有对应helper类会主动抛异常的情况,方便在BaseAcitviy 和 BaseFragment的 onSaveInstanceState 和 onRestoreInstanceState 统一添加SaveHelper.save和SaveHelper.recover方法。 1.0.3 优化代码生成,如果一个activity或者fragment中没有有效的@NeedSave注解，但是添加了SaveHelper.recover和SaveHelper.save 方法，现在就不会自动生成这个类的SaveStateHelper类，减少了无用SaveStateHelper类，便于在Base类中统一集成。 2.0.0 去掉NeedSave注解中的isParcelable字段，自动可以支持不同类型; 如果字段被标记为private在编译的时候会抛异常; 支持基本所有bundle可以传入的类型,包括SparseParcelableArray等, 如果传入的类型bundle不支持会抛异常（如果有遗漏的类型，请在github 提出issue）; 2.0.2 修复通过继承去实现Serializable的对象不能识别的bug; 2.0.3 优化异常提示 2.0.4 修复枚举类型保存的时候不能识别的问题 2.1.0 增加对PersistableBundle的支持,NeedSave注解中设置isPersistable = true则说明该参数保存到PersistableBundle 2.2.6 增加对自定义view的数据保存以及恢复 3.0.0 增加autosave plugin，省去SaveHelper.save 和 SaveHelper.recover的调用 3.0.6 简化引入方式 3.0.7 添加对kotlin的支持 4.0.2 迁移至jitpack,支持gradle tools 4.0+
