------------------------------------------------------------------------------
  
  The guarantees made to the user will be determined based on the position of 
the streaming operator in the pig script. The following types will be supported:
  
-    * *unordered* - no guarantees on the order in which the data is delivered 
to the streaming application
+    * '''unordered''' - no guarantees on the order in which the data is 
delivered to the streaming application
-    * *grouped* - the data for the same key is guaranteed to be processed 
contiguously on a single node
+    * '''grouped''' - the data for the same key is guaranteed to be processed 
contiguously on a single node
-    * *grouped and ordered* - date is grouped and sorted within a group on 
user specified key.
+    * '''grouped and ordered''' - date is grouped and sorted within a group on 
user specified key.
  
  In addition to position, the data grouping and ordering can be determine by 
the data itself. For now, users would need to know the property of the data to 
be able to take advantage of its structure; however, eventually, this should be 
part of metadata.
