1.-Here we create 3 local vector3's representing 3 different sizes for use when animating
	the gui node size property.

2.-getshape() function gets our slice-9 gui node then an if statement is used to check
	the shape_number variable and animate_size is set accordingly and shape_number is
	changed for the next shape.

3.-The function animate_size() takes in the node and shape vector3 and uses them
	with gui.animate. Here we animate the "size" of the node and after the animation is
	complete getshape function is called again and a different shape "size" will be animated
	once again.

4.-In the initialize function we set self.shape_number to 1 and call getshape function to
	start the looping chained animation.
