--------------------------------------------------

  Streaming can have three separate meaning in the context of Pig project:
  
   1. A specific way of submitting jobs to Hadoop: Hadoop Streaming
-  2. A form of processing in which the entire portion of the dataset that 
corresponds to a task in sent to the task and output streams out. There is no 
temporal or causal correspondence between an input record and specific output 
records.

   3. The use of non-Java functions with Pig.
  
  The goal of Pig with respect to streaming is to support #2 for (a)Java UDFs, 
(b)non-Java UDFs and (c)user specified binaries/scripts. We will start with (c) 
since it would be most beneficial for the users. It is not our goal to be 
feature-by-feature compatible with Hadoop streaming as it is too open-ended and 
might force us to implement features that we don't necessarily want in Pig.
