#The Ratter plugin is, essentially, a one room auto-ratter.
#It keeps track of the rats in your inventory, as well as how much you have earned so far.
#It will send these variables on to kmuddy as the following variables,
#so you can make status variables or guages or what have you
#   current_rat_count (Total rats collected so far)
#   total_rat_money (Total money you will earn after selling the rats)

#This has currently been customized for the Jester class and for ratting in Hashani.
#Further configurability to come.
