16 // A set of lightweight wrappers which simplify access to Feature protos.
20 // So accessing feature values is not very convenient.
22 // For example, to read a first value of integer feature "tag":
23 // int id = example.features().feature().at("tag").int64_list().value(0)
39 // To copy multiple values into a feature:
46 // NOTE: Due to the nature of oneof proto fields setting a feature of one type
47 // automatically clears all values stored as another type with the same feature
62 // This will create a feature list keyed as "images" with two features:
67 // feature { float_list { value: [4.0] } }
68 // feature { float_list { value: [5.0, 3.0] } }
