-/**
-Stores formatting information for converting variables into strings. Can be
-applied to an std::ostream or fed to lexical_cast. Also used internally by
-Formatter.
-
-Formats can be constructed from printf-style conversion specifications, by
-chaining calls to the various setter functions, or with a mixture of both.
-
-Since type information for conversions is acquired through templates, the
-meaning of the conversion specifier character is reduced to only specifying
-what the conversion should look like. Of special note is the s conversion,
-which will result in a default conversion for any data type. Size modifiers
-are not supported and there is no difference between signed and unsigned
-conversions.
-
-Some new conversions are supported:
-
- b/B Binary integer conversion
- P Uppercase pointer conversion (like %#X)
