Hoon 101 Assignment 3B

:: I managed to figure out how to get a simple
:: atom-only list checker running, but I struggled 
:: to figure out how to get strings rendered as their
:: initial textual aura instead of @ud-type output
::
:: I was curious why I needed to use '2' as my count
:: number, as other examples I saw in the tutorial (snag.hoon)
:: allowed the user to specify their "selection point
:: and have it represented in the output just fine, i.e:
:: using an input of "3" in snag.hoon would actually get the third list item.
