   * Implementation for the translation of Logical Plan into Physical plan
   * Implementation of the Stagification Process which converts the Physical 
Plan into multiple Map Reduce stages and submits each one as a separate job to 
the cluster
  
- The idea for the translation of Logical Plan to Physical Plan is to put a 
generic infrastructure in place without any ties to the implementation of the 
operators. Once the infrastructure is in place, we can develop the operators 
and the stagification parallely.
