> compare to jackson protobuf:
>  * can parse protobuf 3 proto file
>  * support protobuf 3: map/any
> compare to protoStuff runtime:
>  * for a proto message type, not only support strong type(Pojo), but alse support weak type(Map)
>  * support "any" type
>  * support generic pojo type, eg:CustomGeneric<User>
> compare to standard protobuf:
>  * extend "any" type, for standard not support cases, use "json" schema to codec it.
> compare to all:
>  * just pojo, no need any code generation and annotation
>  * one pojo can serialize to different version proto file to support different version server
>  * wrap List<List<X>>/List<Map<X, Y>>/Map<X, List<Y>>/Map<X, Map<Y, Z>> to standard proto idl, makes model more flexible
>  * support text data come from http,can serrialize from different data type
>  ** number fields (int32/int64 and so on)
>  *** number
>  *** String
>  *** String[]
>  ** string fields
>  *** string
>  *** string[]
>  ** bool fields
>  *** boolean
>  *** string
>  *** string[]
