+/// <summary>
+///  Extensions for Guids
+/// </summary>
+/// <remarks>
+///  in general GUIDs are just unique numbers.
+///  
+///  but there are times where we want the unique numbers to 
+///  always be the same between migrations (e.g new GUIDs for new properties)
+///  
+///  this way if you re-migrate the content stays the same between migrations
+///  makes migrations quicker. and more repeatable.
+/// </remarks>
