daemonized send.py script. updated setup.py

added version file. removed netspeed.sh in favor of a python version.

removed tests for now, as there are none.
Added shoal_agent startstop script and config.

Modified nearest squid algorithm. If there are multiple squid at same
location it will return ip of squid with lowest load value.

Modified load data sent, as we only really care about the network
traffic out of the squid for the time being and not the network in.
