	3 controls that just manipulate ui.Button's attrs
	
	This is more proof of concept rather than finished code.  
	
	I Normally try and make a class out of everything. a little stupid!
	Sometimes functions are very nice. a learning curve.
	
	not sure what you think, but the concept here, i think is quite nice.
	
	if you are good at python, i am sure you are saying something like,
	NO SHIT sherlock. 
	
	Anyway, i am still trying...
