+・判定(xBN±y>=z[c,f])
+　xD6の判定。クリティカル、ファンブルの自動判定を行います。
+　1Dの場合はクリティカル、ファンブルなし。2Dの場合は6ゾロと1ゾロのみクリティカル、ファンブルになります。
+　クリティカルとファンブルが同時に発生した場合、自動的に相殺されます。
+　x：xに振るダイス数を入力。
+　y：yに修正値を入力。省略可能。
+  z：zに目標値を入力。省略可能。
+  c：クリティカルに必要なダイス目「６」の数の増減。省略可能。
+  f：ファンブルに必要なダイス目「６」の数の増減。省略可能。
+　例） 3BN+4　3BN>=8　3BN+1>=10[6]
