Detailed Description

template<typename T>
class utl::Singleton< T >

Curiously Recurring Template Pattern (CRTP) for Meyers singleton.

The singleton class is implemented as follows

#include <utl/Singleton.h>

class SomeClass : public utl::Singleton<SomeClass> {
  ...
private:
  // prevent creation, destruction
  SomeClass() { }
  ~SomeClass() { }

  friend class utl::Singleton<SomeClass>;
};

Singleton automatically prevents copying of the derived class.
