add a base virtualenv and additions

to use:
- run the script 'setup.sh' as root
- when complete, source the activate file
 - how to source a file:  . activate

This should let you remove the file daemons.py as its now included
in the requirements.txt file, which holds external python deps
capture_datad.py works now

added building the netflow package into setup.sh so it would work
in the virtual env
forgot to add pika, added it
