Detailed Description
template<typename T>
class carl::Singleton< T >
Base class that implements a singleton.
A class that shall be a singleton can inherit from this class (the template argument being the class itself, see CRTP for this). It takes care of
- deleting the copy constructor and the assignment operator,
- providing a protected default constructor and a virtual destructor and
- providing getInstance() that returns the one single object of this type.
