ConfigReader is a set of classes for reading configuration files.

ConfigReader is a set of classes for reading configuration files.  The
programmer can easily specify the directives to be read, as well as
their default values and a parsing function or method to use.  A lot
of work went into error handling.  The class implementation means that
a simple subclass can be written to parse a different style of
configuration file, and it will automatically get the specifying,
error handling, and parser features of ConfigReader.
