* Explained:
* The operator | means or.
* In an If...Else statement it would look like this:
* <code>
* bool A = true;
* bool B = false;
* if (A == true || B == true)
* {
* Console.WriteLine("A or B is true");
* }
* </code>
*
* To add a flag to an enum use |= (Or is)
*
* I'm not such an expert to tell you how it works in detail however, it has something to do with bit comparing. (Refer to Wikipedia.)
