Using a proxy

Hello. I was wondering if you could add an option to the install script that allows the use of a proxy. I work at Los Alamos National lab and we use a proxy here. Upon getting the following error when running the quickinstall.sh script, I feel like there might be an issue with our proxy:
Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'NewConnectionError(': Failed to establish a new connection: [Errno 101] Network is unreachable',)': /simple/futures/

If it's a different problem please let me know. Any help would be great. I'm running the script on a RHEL 7 virtual machine.

Start by reading quickinstall.sh and tracing how it invokes pip when installing dependencies. Determine how a proxy option should be supplied to that install path, then verify that the script can complete dependency installation through the proxy on the reported RHEL 7 environment.
