+        About:
+        I searched a function to compare arrays and the array_diff()
+        was not specific enough. It ignores the order of the array-values.
+        So I reimplemented the diff-function which is found on unix-systems
+        but this you can use directly in your code and adopt for your needs.
+        Simply adopt the formatline-function. with the third-parameter of arr_diff()
+        you can hide matching lines. Hope someone has use for this.
