Bound to Constraint Conversion Functor. In many cases one has bounded problems that is to say that we have some problem subject to the constraints
x l x u
Or more generally the bounds could be dependent on x, that is
x l(x) x u(x)
In some problems the bound functions l(x) and u(x) would be passed directly to some solver. However, in other cases a solver or method may work with a more general ``constraint'' function. That is we can rewrite either the lower or upper bounds into a inequality constraint of the type c(x) 0,
c(x) = u(x) - x 0 or c(x) = x - l(x) 0
This is the purpose of the template class, it takes a bound function and makes it behave as a constraint function.
