+ * Below are all of the individual atoms that are logged by Android via statsd

+ *
+ * RULES:
+ *   - The field ids for each atom must start at 1, and count upwards by 1.
+ *     Skipping field ids is not allowed.
+ *   - These form an API, so renaming, renumbering or removing fields is
+ *     not allowed between android releases.  (This is not currently enforced,
+ *     but there will be a tool to enforce this restriction).
+ *   - The types must be built-in protocol buffer types, namely, no sub-messages
+ *     are allowed (yet).  The bytes type is also not allowed.
+ *   - The CamelCase name of the message type should match the
+ *     underscore_separated name as defined in StatsEvent.
+ *   - If an atom represents work that can be attributed to an app, there can
+ *     be exactly one WorkSource field. It must be field number 1.
+ *   - A field that is a uid should be a string field, tagged with the [xxx]
+ *     annotation. The generated code on android will be represented by UIDs,
+ *     and those UIDs will be translated in xxx to those strings.
+ *
+ * CONVENTIONS:
+ *   - Events are past tense. e.g. ScreenStateChanged, not ScreenStateChange
+ *   - If there is a UID, it goes first. Think in an object-oriented fashion.
