Serialization for D part 1.1 of N: comments

This is as much notes to my self as anything:

• Thanks to Chad for pointing out that I need to consider what license I will be using. (I'm planning of being very permissive there.)
  
• Several other people have pointed me at their own work. I guess I'll have to check what license they use. OTOH, while I really want to make a good usable library, this is just as much a "lets have fun with template" project.
  
• Tim Matthews pointed out another source/sink I will want to consider: databases. Being able to use a byte array would cover that one I think.
