Detailed Description

template<typename Pointer>
struct theplu::yat::utility::Dereferencer< Pointer >

Adaptor between pointer and pointee interface.

Functor takes a pointer and returns a reference to the instance
pointer is pointing to. Return type is decided by <a
href=http://www.sgi.com/tech/stl/iterator_traits.html>
std::iterator_traits<Pointer>::reference </a>. Pointer must have
an \c operator*, i.e., \c Pointer can be a traditional pointer or
an <a href="http://www.sgi.com/tech/stl/InputIterator.html">Input Iterator</a>.

The class is designed to be used with boost::transform_iterator

     std::vector<MyClass*> vec;
     ...
     Dereferencer<MyClass*> dereferencer;
     std::set<MyClass> s;
     s.insert(boost::make_transform_iterator(vec.begin(), dereferencer),
              boost::make_transform_iterator(vec.end(), dereferencer))

where elements in vec<MyClass*> are copied in to set<MyClass>.
