	/*
	A simple class which allows you to perform extensive traces with line numbers.
	
	@author :
	Dinu Bogdan Gabriel - badu@badu.ro
	
	Usage example:
	
	protected function someMethod():void
	{
	
		var myArrayCollection : ArrayCollection = new ArrayCollection();
		myArrayCollection.addItem({firstname:"test1" , lastname: "test2"});
		myArrayCollection.addItem({firstname:"test3" , lastname: "test4"});
	
		Tracer.log( new Error() , myArrayCollection , true);	
	}
	
	public static function log( source : Error , message:Object=null,  isObjectUtilDump : Boolean = false ):void
	
	Parameters : 
	source : Error - the place where the trace comes from, usually using "new Error()" will provide all the info you need, regardless of the
							type of class / method
	message - the message you want to trace. Can accept complex objects which in combination with isObjectUtilDump= true will
							use ObjectUtil to dump it all
	isObjectUtilDump - see above
	
	Important Note : 
	
		1. do not forget to set compiler param -define CONFIG::AIR_LOG false if you are using it as it is
		2. I recommend you to use -define CONFIG::DEBUG true too and do conditionals on traces that are "permanent" (remains there until you deliver)
