    A little 2to3 refactoring #3637

    This moves command line logic from refactor.py to a new file called
    main.py.  RefactoringTool now merely deals with the actual fixers and
    refactoring; options processing for example is abstracted out.

    This patch was reviewed by Gregory P. Smith.
