Ouilookup will either:
Take a full or partial MAC as a sole argument and comb oui.txt for that MAC. When found, it spits out the owner organization
or
Take --update as a sole argument and either download oui.txt from the IEEE if it does not exist, or download a temp (oui2.txt), compare the two, and keep the new one if it is different than the local file
Please note that this is still a work in progress and things may break
This repo is still called "macouiscriptS" because I used to have the functionality in --update split off into a separate script
