Detailed Description

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

This template class pattern provides a traditional Singleton pattern (see GoF). Allows you to designate a single-instance global class by inheriting off of the template class.

class MyClass: public Singleton<MyClass> ...

The class will need to provide either a public or a protected friend constructor:

friend class Singleton<MyClass>;

This implementation is not thread safe.
