Q: How do i get rid of Soundflower on Yosemite?

I just downloaded sound recording app, Soundflower 2.0b2 on a mac laptop running Yosemite 10.10.5 

it doesn't show up in my applications folder at all. But when i open System Prefs, it's listed as an input and output. I don't want this program - i don't want it screwing up my computer but how can i get rid of any of these invisible files?

there's an Uninstall Script - i hit the "run script" arrow button in the header but it didn't remove the preference from my system prefs. it's confusing - i've never used an uninstaller like this. it has options for Apple Script and Java Script "on run".  I get a prompt for my password - type it in and it says "Done!" under the Result column. ??
