[boost] Idea for numeric types

This is for numeric types that model real numbers.

Numeric types use operator++ to update an object to its current value 
plus one.  For integral types, this is equivalent to getting the next 
representable value.  This is not true for non-integral types.  I think 
the non-integral real types that are built-in or in Boost (like 
boost::rational) use the plus-one meaning of operator++.  However, they 
may not have functions to update to the next representative value.  I 
think IEEE and C99 define such functions for the built-in floating 
types.  We should do something for our numeric types.  (I don't think 
the next-rational is easy to determine.)

Of course, we need to define similar stuff for operator--.
