A command line tool for Gameroom

/*
This is a modified version of the "ratioOut" script. I modified it to output game prices instead of ratios.
I created it to be able to make line-of-sight adjustments to the buy-in values of Junk/Overstock titles
without having to manually tag them all first. Pandemic pricing pushed sell values higher, which in turn
increased buy-in values higher, but we don't want to pay more for Junk/Overstock titles. -DH 8/3/21
