/**
* API for associating tags with scoped operations.
*
* <p>This package manages a set of tags in the {@code io.grpc.Context}. The tags can be used to
* label anything that is associated with a specific operation. For example, the {@code
* io.opencensus.stats} package labels all stats with the current tags.
*
* <p>{@link io.opencensus.tags.Tag Tags} are key-value pairs. The {@link io.opencensus.tags.TagKey
* keys} and {@link io.opencensus.tags.TagValue values} are wrapped {@code String}s. They are stored
* as a map in a {@link io.opencensus.tags.TagContext}.
*
* <p>Note that tags are independent of the tracing data that is propagated in the {@code
* io.grpc.Context}, such as trace ID.
