XY,H,M2,M3,W,S,L1,L2,L3-Wing method added, which is an AIC of 3 strong and 2 weak links.

Added an extra "0"-button to manual erase a clue from a cell

Changes version 5 Nov 2023, 2023-11
Repaired the 2 bugs in WXYZ-method
Type B was too restrictive
Type C was with only 1 cell in each wing, is now with only 1 Z-cell in each wing.
Still not "grouped" and because it is a multiple recursive subroutine it is possible that a VWXYZ is found earlier than a WXYZ.
More manual functionality like
Add clues or eliminating candidates/clues in a chosen cell.
Highlight all cells with a chosen clue.
Changes version 1 Sep 2023, 2023-9
Method XYZwing was always omitted during puzzle solving. Fixed.
