WIP: Better Wrapper Script

[Zalgo2462]

Fixes #50.

The documentation will need to be updated to match the new wrapper script interface.

How much direct contact do we want to allow the user to have with docker compose?
If we allow too much contact, things will get confusing fast.
If we don't allow enough, we might need to use separate scripts to administer the system.

ipfix-rita -h
IPFix-RITA. Collect Netflow Records and Ship them to RITA for Analysis.
Usage: ipfix-rita command [args]

@SamuelCarroll Before I update the documentation. Could you please review this PR where it is now. That way if I need to change any of the commands, I don't have to edit the docs a second time.

Sorry about taking so long to get to all of these. When I was running the installer to check this I have the following error
Unknown command: up
Could you check if that's just my machine?

It looks like the line "$INSTALLATION_BIN_DIR/ipfix-rita" up --no-start command during needs to be changed to docker-compose -f $INSTALLATION_LIB_DIR/docker-compose/main.yaml up --no-start.

I'd like to wait on making that change until the outstanding PR for #54 is merged.
