* The arg_hdr struct defines properties that are common to all arg_xxx structs.
* The argtable library requires each arg_xxx struct to have an arg_hdr
* struct as its first data member.
* The argtable library functions then use this data to identify the
* properties of the command line option, such as its option tags,
* datatype string, and glossary strings, and so on.
* Moreover, the arg_hdr struct contains pointers to custom functions that
* are provided by each arg_xxx struct which perform the tasks of parsing
* that particular arg_xxx arguments, performing post-parse checks, and
* reporting errors.
* These functions are private to the individual arg_xxx source code
* and are the pointer to them are initiliased by that arg_xxx struct's
* constructor function. The user could alter them after construction
* if desired, but the original intention is for them to be set by the
* constructor and left unaltered.
