The basic labeled argument that parses a value.
This is a template class, which means the type T defines the type that a given object will attempt to parse when the flag/name is matched on the command line. While there is nothing stopping you from creating an unflagged ValueArg, it is unwise and would cause significant problems. Instead use an UnlabeledValueArg.

You could conceivably call this constructor with a blank flag, but that would make you a bad person. It would also cause an exception to be thrown. If you want an unlabeled argument, use the other constructor.

name | - A one word name for the argument. Can be used as a long flag on the command line. |

req | - Whether the argument is required on the command line. |
value | - The default value assigned to this argument if it is not present on the command line. |

The single char flag used to identify the argument.
This value (preceded by a dash {-}), can be used to identify an argument on the command line. The _flag can be blank, in fact this is how unlabeled args work. Unlabeled args must override appropriate functions to get correct handling. Note that the _flag does NOT include the dash as part of the flag.
