/*
	_currentAction and _nextAction:
	
	At any time, _currentAction contains an action index (defined above). The current
	action index is what the claw is doing right now. If the player presses a button
	before the current action completes, _nextAction saves the new action and input
	is disabled. This has the effect of implementing a queue of commands for the claw
	that can save at most one extra command.
	
	The general strategy for using _currentAction and _nextAction are:
	--	If the player presses a claw button and _currentAction is kNoActionIndex,
		do the command immediately and set _currentAction accordingly.
	--	If the player presses a claw button and _currentAction is not kNoActionIndex,
		save the appropriate action index in _nextAction.
	--	When a command animation completes, set _nextAction to kNoActionIndex, then
		check if _nextAction has a command waiting in it. If so, play the appriate
		animation, copy _nextAction into _currentAction and set _nextAction to
		kNoActionIndex.
	--	If the player tries to get up, disable input (including all claw buttons) until
		the player rises. Then, if the claw is in its original position, play the
		animation of the player rising.
	--	If the claw needs to be put back, play the first move required to put the
		claw back by setting _currentAction and playing the appropriate animation.
		Leave _nextAction alone. When the animation, completes, check to see if the
		claw is in its original position or not. If so, complete the player rising
		sequence by playing the rising animation. If not, repeat this whole step.
	
	Using this general strategy allows the use of a single function,
	DispatchClawAction, which can both cause the claw to perform a command and saving
	the next command in _nextAction.
