Detailed Description

Static class to handle singletons of a given type and priority.

The special issues for these Singletons are:
1) it's a template class - can be used for every type
2) they have a priority used for destroying the Singletons AFTER the application ends:

• singletons are deleted in ascending order of int values (0 first, INT_MAX last)
• singletons of the same priority are deleted in the opposite order they where created (LIFO) By this, one can count for dependencies of destroying objects, e.g. general objects as the log module to be deleted latest.

 Singletons::get < MyClass, INT_MAX - 1 >

This generates a Singleton of MyClass with highest priority
