Parses the given arguments according to this parser's rules. An exception will be
thrown if any rule is violated.

Note: This function uses a reference to modify the given $argv array. If no argument
values are provided a copy of the global $argv array will be used.

@param   array   $argv       The command line arguments
@return  array               Anything still present in $argv that wasn't matched by a rule
@throws  Exception
