      HIVE-186 . Refactor code to use a single graph, nodeprocessor, dispatcher and rule abstraction. (Ashish Thusoo via zshao)

    Description

      Currently, the query processor has two different tree and rule abstractions - one for ASTs and one for Operator Graphs. We should clean this up so that we have a single abstraction that can be reused at different stages in the query compiler.
