Option - Abstract representation for a single form of driver argument.
An Option class represents a form of option that the driver takes, for example how many arguments the option has and how they can be provided. Individual option instances store additional information about what group the option is a member of (if any), if the option is an alias, and a number of flags. At runtime the driver parses the command line into concrete Arg instances, each of which corresponds to a particular Option instance.

accept - Potentially accept the current argument, returning a new Arg instance, or 0 if the option does not accept this argument (or the argument is missing values).
If the option accepts the current argument, accept() sets Index to the position where argument parsing should resume (even if the argument is missing values).
| ArgSize | The number of bytes taken up by the matched Option prefix and name. This is used to determine where joined values start. |

| bool Option::matches | ( | OptSpecifier | ID | ) | const |
matches - Predicate for whether this option is part of the given option (which may be a group).
Note that matches against options which are an alias should never be done – aliases do not participate in matching and so such a query will always be false.
