virtual destructor and a virtual clone function (a virtual constructor),
so that derived classes can provide these functions.

\brief Abstract base class for warm start `diff' objects
For those types of warm start objects where the notion of a `diff' makes
sense, this virtual base class is provided. As with CoinWarmStart, its sole
reason for existence is to make it possible to write solver-independent code.
