Wrong tiles connecting each-other / Fix proposal

As they say, an image worth a thousand words.


We are having an issue were tile 5 connects to itself and so does 4 in a weird way. My solution idea is to have a tile have 2 properties, not only edge names, but also "connects to"

Hopefully the image explains the idea better that I could do by describing it.

(Notice that "ABB" in the connects to would really connect to what is "BBA" on the image, because of how the code works with the "reverse" logic, unless I missed something, but the basic idea is there even if I mistake some cases)

まず、既存のタイルエッジと逆方向ロジックの処理を追跡します。この issue には誤った接続を示す画像がありますが、ソースファイルやテストの名前は示されていません。提案された connects-to 関係が現在のエッジ名とどのように連携すべきかを判断し、そのうえでタイル 4 と 5 が自分自身に接続されなくなり、意図された関係に従うことを確認します。
