What are Layouts?
• Until now, we only worked with the simplest Node container which
was Pane.
• It’s the simplest one, because we specified the location of our
elements by hand in pixel format.
• Now days, with a great needs of responsive UIs no one is going to
hard code the location of UI elements.
• So we need smarter node container.
• A smart container decides about the location of an element
automatically based on a specified behavior.

Control versus Pane:
• A "Control" is a node in the scene graph which can be manipulated
by the user. Controls provide additional variables and behaviors
beyond those of Node to support common user interactions in a
manner which is consistent and predictable for the user.
• Pane is the base class for layout panes which need to expose the
children list as public so that users of the subclass can freely
add/remove children.
