		/*Constructor	Purpose
		
		FlowLayout()	
		Constructs a new FlowLayout object with a centered alignment and 
		horizontal and vertical gaps with the default size of 5 pixels.
		
		FlowLayout(int align)	
		Creates a new flow layout manager with the indicated alignment 
		and horizontal and vertical gaps with the default size of 5 pixels. 
		The alignment argument can be FlowLayout.LEADING,
		FlowLayout.CENTER, or FlowLayout.TRAILING. 
		When the FlowLayout object controls a container with a left-to right component 
		orientation (the default), the LEADING value specifies the components 
		to be left-aligned and the TRAILING value specifies the components to be right-aligned.
		
		FlowLayout (int align, int hgap, int vgap)	
		Creates a new flow layout manager with the indicated alignment and 
		the indicated horizontal and vertical gaps. 
		The hgap and vgap arguments specify the number of pixels to put between components.*/
