//             PUZZLE OBJECT
//---------------------------------------------------------
/*****************************************************************************/
/*QUAKED puzzle_object (0 0.5 1) (-16 -16 0) (16 16 32) 

Puzzle object is the basic framework for all the puzzles. It communicates 
with the script through events and threads to process the puzzle state.
All logic for the puzzle object exists in the script. 

The puzzle object contains four threads, which are ItemUsed, Solved, Canceled and Failed. 
These are explained in the Key Value Pairs section. The Puzzle object also contains an 
item used string. This allows the level designer to specify the item the player must 
use to activate the puzzle. 

Key Value Pairs:
model						 <model name>	- the tiki model to use for the puzzle object
puzzleobject_opendistance	 <distance>		- the amount of distance the player should be before the puzzle opens.
puzzleobject_itemtouse		 <item name>	- the name of the item the player must use to execute the puzzle
puzzleobject_itemusedthread	 <thread name>	- the name of the thread called when the item is used.
puzzleobject_failedthread	 <thread name>	- the name of the thread called when the puzzle fails
puzzleobject_canceledthread	 <thread name>  - the name of the thread called when the puzzle is canceled
puzzleobject_solvedthread	 <thread name>	- the name of the thread called when the puzzle is solved.
