/*******************************************************************
	* SCORM 2004 API Search Algorithm
	* Description - Improvement of the algorithm developed by ADL to 
		find the SCORM 2004 API Adapter. The improvements eliminate 
		errors, improve code clarity and eliminate the dependence
		on global variables. The errors removed include:
			- The "win" variable was never declared in a scope 
			  accessible to the GetAPI function
			- A call to API.version which is not part of the SCORM
			  2004 specification
			- The previous algorithm was not able to find the API
			  if it was located in the window's parent's opener
