  It removes TLazDockSplitter, TLazDockPage and TLazDockPages if they are no

 Examples:

  Search Order:

  1. A TLazDockSplitter dividing only two controls:

     Before:
     |-------------
     | +--+ | +---
     | |  | | | B
     | +--+ | +---
     |-------------

     The splitter will be deleted and the right control will be anchored to the
     left.

     After:
     |-------------
     | +---
     | | B
     | +---
     |-------------


  2. Four spiral splitters:

       | +--+ |  C

              |

              |   D


  3. No TLazDockSplitter. Control is the only child of a TLazDockPage
     In this case the page will be deleted.
     If the TLazDockPages has no children left, it is recursively undocked.

  4. No TLazDockSplitter, Control is the only child of a TLazDockForm.
     The TLazDockForm is deleted and the Control is floated.
     This normally means: A form will simply be placed on the desktop, other
     controls will be docked into their DockSite.

  5. Otherwise: this control was not docked.</pre>
