Testing out for possibles matching pattern and see if everything work over and over as expected.

The matching system will find 3 adjacent puio within same color for group tagging thus form “island cluster”. Since the game need at least four puio to fully match, a puio (same color) near those three need to be find and added to island group then make them into “four”

Found out that this “three & four” flood-fill really works without comparing value in array. Just overlapping test. Array used only for storing existing stacking level for each column in this scenario.
