Added a basic test on empty parametes processing.
Added wheel support

It appears to produce a workable wheel file. However, I am doing
something wrong with the MAKEFILE.in and bdist_wheel fails to include
examples and docs in the whl file.
Moved the .so files inside the pydoop folder.

This is to simplify support of wheel packaging. It will also help in the
self-contained example.
Makefile now uses wheel.
Added conditional dependency on argparse.
Makefile now uses wheel for packaging.
Updated self_contained example.

Now it uses pydoop submit and wheel packaging.
Bug fixes.

Forgotten cache and egg related flags havoc.
Added a build target.

And made all the install target depend on it.
Added wheel creation to .travis.yml

Commented out, for the time being, the CDH targets.
more debugging support
aligned with origin
