Numerous changes

I updated the README.md to include a section about development.

I cleaned up backupy.py.
I finished the copy function in backupy.py and raised the version number
to 1.0.

I created a sub directory named backupy1.0 containing a cleaned up
version of the source code in backupy.py and SETUP.py. I also moved over
__INIT__.py to make things work when I fix the install script.
