This template class describes the minimum and maximum values for
the differnet data types.
It a substitute for the <tt>numeric_limits</tt> class described in the
ISO/ANSI standard (chapter 18.2.1.1), as most compiler still do not support
this feature (or more precisely: the header file \<limits\> is not implemented).
If \<limits\> exists, Limits is just a wrapper around the <tt>numeric_limits</tt> class,
otherwise it returns the value from the standard C header \<limits.h\>. \par
