-- L_COUNTDOWN_DESTROY_AI.lua

-- Allows AI to establish a suicide countdown behavior useful
-- for situations when AI are created from other objects 
-- (statues, eggs, etc.)
-- Created abeechler... 2/3/11
-- updated by brandi... 6/7/11 - added a check to see if the enemy is aggroing on the player before just killing it
-- updated by brandi... 8/25/11 - if the enemy is aggroed on the player when it should die, it starts a timer to see if the player is actually fighting that enemy
