 I'll try to sum up only the major changes below._
 
 - The demo has been completely remade
 - Added new beans and properties
 - Added new mechanisms for bindings
-- Added new collections, in particular an ObservableList that combines the capabilities of JavaFX's FilteredList and SortedList.

 Also those two are read-only, but MaterialFX also offers a version that allows to directly make changes to the source list
 - ReactFX, Flowless removed in favor of my own Virtual Flow implementation, VirtualizedFX. As a result all controls having lists have been reworked.
 - The table view has been reworked as well to use a Virtual Flow (scrollable) so it's efficiency is now on a whole new level. There's also a paginated
