#  * This script automatically adds a state evolution feat. Let's say a zombie #
#    bit you well at first your just 'Scarred' then after one turn the state   #
#    is removed automatically, and a new one is added. Now your 'Feverish'     #
#    and so on until your 'One of Them'. Or lets say you have a transform      #
#    system based on states. Now when you are done with your 'Werewolf Form'   #
#    three turn killing spree, it is removed and now you are back to           #
#    'Human Form'. You can even use the 'Death' state.                         #
#                                                                              #
