Readable serializer

That support having comments to the serialized content (when deserializing). This way it can be used in annotated config files etc. It should use a tokenizer similar to that of thrift itself (see thrift tokenizer in providence-reflect). E.g.:

{
    # a field with a normal value, may be separated / ended with optional ',' or ';' character.
    my_field: 355
    // comments can also be 'c' style.
    an_array: [ "it", "is", "not", "important" ]
}
