Oops, I'll fix this.

I will add them.

I'll fix this.  (How do others spell check html?)

I'll fix this too.

I don't have a preference.  The create function was done this way so
that it could take a block of memory and not just strings, but thinking
about it now, void* would be better for this.  It does not sound like
this is useful and I should just have the function take a
std::basic_string.  I've also considered changing this to a function
object similar to basic_uuid_generator instead of a static function. 
What do people want?

With your permission, I'll include your example.

I will suppress these warnings as in your example.

I will fix this.
