Description:  This is a movingbanner app that can display a moving flag with custom content. The user can customize their banner
colors and text size. This is also develop through using javafx. It uses the combo box, Rectangle class, animation class, and other 
common use javafx data type. After the ok button is clicked, the banner will keep moving from the left to the right horizontally
until the user exit the program. Those buttons actions are created by using action handle classes. The color is controlled by the
built in color functions in the scene class and the text size is controlled by the css functions.
