+Feature:
+  Instrumentation of nytimes usage and clicks on recommended areas
+
+30000 feet view:
+  - We decided to implement this feature by collecting nytimes visits from places.
+  - Each visit will carry timestamp, visitId and fromVisitId in addition to already existent fields
+  - Then addon will collect such visits into an array
+  - This array will be placed in storage, flushed by Collector to the backend, and then cleaned
+  - Since the triple (timestamp, visitId, fromVisitId) uniquely identifies each visit, the analytics
+    can always replace corresponding rows into a database table, he
+
+  The collection will happen in HistoryReader:
+  - An instance  of a HistoryVisitor is passed to the HistoryReader
+  - HistoryReader presents visit information to the Visitor
+  - A subclass NYTimesHistoryVisitor will accumulate nytimes visits info into storage
+  - Dispatcher sends NYTimesHistoryVisitor storage to backend and cleans the storage
