+  This in an HTML Import-able file that contains the definition
+  of the following elements:
+
+    <bot-page-data>
+
+  This makes calls authenticated with Oauth 2 to the swarming apis.  It parses
+  that data into usable data structures.
+
+  Properties:
+    busy: Boolean, if we are fetching any data from the server.
+    bot: Object, The information about the bot. See swarming_rpcs.py#BotInfo
+        for all relevent fields.
+    events: Array<Object>, The most recent events that pertain to this bot.
+        Contains the following fields: "event_type", "message", "ts" (timestamp),
+        "quarantined", "version".
+    tasks: Array<Object>, The most recent tasks done by this bot.
+        Contains the following fields: "abandoned_ts", "bot_version", "duration",
+        "failure", "internal_failure", "modified_ts", "name", "started_ts",
+        "state", "task_id", "try_number".
+
+  Methods:
+    request(): Force a fetch of the data. This happens automatically when
+        auth_headers is set or bot_id is changed.
+
+  Events:
+    None.
