Refactored script to be a front end to submit.
Fixed a typo in run_wordcount_full

Added some debugging support. Disabled examples/pydoop_script for the
time being.
Merge branch 'script_refactoring' into develop
All the script examples now use the cmd line tool.

Now we explicitely show how to use the pydoop script.
All the tests on the results have been temporarily removed.
Merge branch 'script_examples' into develop
Re-enabled script examples.
Fixed a bug in a shell script.
Fixed a bug in argparse.

Added a workaround for a bug in argparse. If fromfile_prefix_chars is
not None, argparse will choke on zero lenght parameters.  This will
happen if, for instance, someone uses the pydoop script -t '' flag to
indicate an empty key-value output separator.
