Data Format
Commands for setting value formats and value parsers.
Formats
Formats define how values are displayed based on the value type or format name.
If format has a name, other commands can choose to use this format by referring to it by this name. Leaving the created format nameless declares it as the default format for specific value type. Any command that prints out a value type will then use this format, unless the command specifies a named format for itself.
Parsers
Parsers define how values are parsed from string to value type.
