Assign the hzDomain to an domain name held in a character string Note: This function will record an E_FORMAT error if the supplied cstr did not amount to an domain name

Function Logic:

Function body:

   //  
   //  Arguments: 1) cpStr A null terminated string assumed to be an domain name
   //  
   //  Returns: Reference to this email adress instance in all cases.
   //  
   //  Note: This function will record an E_FORMAT error if the supplied cstr did not amount to an domain name
