	Q: Purpose and usage of this method?
	
	A: Whenever you want to fetch the mouse co-ordinates (X and Y positions) 
		1. Attach this script file to the source file
		2. Call this method for the "onmousemove" event which is the 'document' property, as follows...
	
			var mouseXYCoordinates = "";
			document.onmousemove = function(event){
				mouseXYCoordinates = getMouseXY(event); // This call will come here and executes the following defined code
			}
			
			Note: This method finds out the mouse X and Y positions and returns the result as <X-Position value> + "," + <Y-Position Value>. 
			Once received you need to separate both X & Y values. Eg: 456,789
