(*
  ich denke mal das beste wäre erstmal die TGradTabPages mit der TGradTabControl
  richtig zu "verlinken", ich habe auch noch ne TabListe hinzufügt diese müsste man dann auch noch
  bei der TGradTabPages einbauen damit die Tabs schon mal automatisch erstellt und
  gelöscht werden ^^

  ToDo:
  - TGradTabBar & TGradTabPagesBar mit sortieren von Tabs "ausstatten"
  - TabPosition einbauen, sowie das zeichnen und anordnen der Tabs/Pages ändern
  - CurrentPage-Button ohne Abstand
  - IDE Testen hoffe es geht *g*
  
  Danach:
  - Eigene Page Classen zu ordnen ( bräuchte ich zumindest ^^ ) - Feddich
  - Tabs disable-n
  - noch welche Wünsche? xD
  - Testen testen testen und voila wir haben eine neue komponente :D
  
  - Irgendwann mal eine TGradDrawer klasse um mehre
