+  This in an HTML Import-able file that contains the definition
+  of the following elements:
+
+    <bot-list-data>
+
+  This makes calls authenticated with Oauth 2 to the swarming apis.  It parses
+  that data into usable data structures.
+
+  Usage:
+
+    <bot-list-data></bot-list-data>
+
+  Properties:
+    // inputs
+    auth_headers: Object, the OAuth2 header to include in the request.  This
+        should come from swarming-app.
+    // outputs
+    bots: Array<Object>, all bots returned by the botlist.
+    busy: Boolean, if the ajax request is in flight.
+    primary_map: Object, a mapping of primary keys to secondary items.
+        The primary keys are things that can be columns or sorted by.  The
+        primary values (aka the secondary items) are things that can be filtered
+        on. Primary consists of dimensions and state.  Secondary contains the
+        values primary things can be.
+    primary_arr: Array<String>, the display order of the primary keys.
+        This is dimensions, then bot properties, then elements from bot.state.
+
+  Methods:
+    signIn(): Force a signin of the user using OAuth.  This happens
+        automatically when auth_headers is set.
+
+  Events:
+    None.
