Detailed Description

template<typename T>
class ostream_printable< T >

With this class, you can make your own classes ostream-printable.

Usage: * derive YourType from ostream_printable<YourType> * implement std::ostream& YourType::print(std::ostream& o) const; * now you can << YourType << and it will use the print() function. see http://en.wikipedia.org/wiki/BartonNackman_trick.
