7 | * Provides singleton functionality in a modular sort of way. Make this the | ||
8 | * base class of any other class and you immediately gain singleton | ||
9 | * functionality. Be sure to make your constructor and various functions use | ||
10 | * intellegent scoping. Cleanup and instantiation are performed automatically | ||
11 | * for you at first use and program exit. There are two things that you must | ||
12 | * do when using this template, first is to inherit from it with the name of | ||
13 | * your class filling in for T and then make this class a friend of your class. | ||

24 | * You can still add public functions and variables to your new Singleton child | ||

26 | * friend decleration). | ||
