HepCmdLine

HepCmdLine is a base class for command line parsing. It uses the HepCmdArg class and its subclasses.

The user interfaces of this class and for the HepCmdArg class were inspired by the CmdLine package written by Brad Appleton . However, the coding is entirely new. It was felt that the CmdLine package was too large and complex when all we wanted was straightforward command line argument parsing.
