Class PCGenPreloader

code/src/java/pcgen/gui3/preloader/PCGenPreloader.java:45–116

This is the application logic for the "Splash Screen" when loading PCGEn It isn't directly the controller for the UI, but interacts the view and interacts with the controller. Once we're 100% on JavaFX can possibly be replaced with the native Preloader, but requires thought. @see pcgen.gui3.JFXPane

 * @see pcgen.gui3.JFXPanelFromResource
