Custom layout for basic block with its instructions and buttons for clicking into successors (No UI logic yet)
Changed CFGView to a composition of BorderPane and inside of it a list view; Clicking on buttons works
Quick and dirty retrieval of basic block number
Selecting and focusing on list view works. The UI does not scroll to the basic
block, though. Further analysis required for fixing this issue
Scrolling to selected basic block index works
Code clean up: Deletion of custom cell, not needed right now
