Added "I:" for "Iteration", to use instead of inconsistent tags

README.md

 *   *msg* is actual message body. It can be used to contain parseable data 
     like `name=john;age=32;state=il;`
 *   *tag* can be used to identify related messages like those from one test
+*   use *i* if you tend to write tags like `test01-002` and `test01-002` to 
+    store the iteration number, you'll be better off with this parameter as 
+    it won't break your ability to use tags
