/**
   This will set up strings to send to MobileEyes so that server
   developers can easily add more information.  There are different
   ways ways you can add a string (they all are the same way
   internally).  The raw way is addString which takes a functor with a
   buffer and a buffer len, the functor then has to fill in the string
   when called.  The other ways are set up for convenience and are
   wrappers in this class around the addString, the other ways are
   addStringInt, addStringDouble, addStringBool, these all take a
   functor that returns the type and a format string (in addition to
   the name and maxLen again).
